Sendgrid-csharp: Async broken in library, causing deadlocks and responses not returning in non-console apps

[hunglee]

Hi,
I'm using the example code to send email on MVC web app but it not response on the line dynamic response = sg.client.mail.send.post(requestBody: mail.Get()); even it has been sent successfully. Am I missing something?

String apiKey = "APIKEY";
dynamic sg = new SendGrid.SendGridAPIClient(apiKey);

Email from = new Email("[email protected]");
String subject = "Hello World from the SendGrid CSharp Library";
Email to = new Email("[email protected]");
Content content = new Content("text/plain", "Textual content");
Mail mail = new Mail(from, subject, to, content);

 dynamic response = sg.client.mail.send.post(requestBody: mail.Get());

Note: the example code work fine on console app only (response after post)

Thanks

[trinathm]

I am also facing same issue. Its working fine with console app. but when integrated with MVC application, its not returning response.

[thinkingserious]

@hunglee thanks for letting us know. We will be digging deeper to figure out what is going wrong.

Any additional details are appreciated.

@hunglee @trinathm Even though the response is not returned, does the email get sent?

[hunglee]

@thinkingserious yes, the email was sent successfully.
The response is also not returned with Web API and Classic Windows Form.
Thanks

[trinathm]

@thinkingserious Yes, Email are being sent successfully, but after posting mail, its not returning response.

[ChrisRacki]

same here...

[joantorres]

@thinkingserious Any estimation on when this bug will be fixed??
I was just integrating this library into a new project and it doesn't work at all, but it's quite urgent and if you don't have a hot fix by tomorrow I will have to go find another alternative.
I tried to use the previous version 6.3.4 but it does not support templates, so it doesn't work for me.
Thanks for the help!

[thinkingserious]

Hello Everyone,

@hunglee @trinathm @ChrisRacki @joantorres @jahmai @walmon

First, thanks for your feedback and patience.

I've done some digging and I can't reproduce in the console app (as mentioned, it seems to work there) so here is what I'm thinking (I would love to get some feedback):

The API call happens here which calls this function.

So perhaps this call dynamic response = sg.client.mail.send.post(requestBody: mail.Get()); should be dynamic response = await sg.client.mail.send.post(requestBody: mail.Get());

Thoughts?

I still have more digging to do, as I don't have an environment where I see this error reproduced (if anyone can help with that, I would be greatly appreciative).

[matthewbcline]

I can reliably reproduce this in a Web API project. Here is my method:

[Route("sendEmail"), HttpPost, AllowAnonymous]
public virtual async Task<IHttpActionResult> SendEmail()
{
    var apiKey = "my api key";
    var from = new Email("[email protected]");
    var subject = "Subject";
    var to = new Email("[email protected]");
    var textContent = new Content("text/plain", "Content");
    var mail = new Mail(from, subject, to, textContent);

    dynamic sendGridClient = new SendGridAPIClient(apiKey);
    // All three of these calls never return. The email message is sent, however.
    dynamic response = sendGridClient.client.mail.send.post(requestBody: mail.Get());
    dynamic response = await sendGridClient.client.mail.send.post(requestBody: mail.Get());
    dynamic response = await (sendGridClient.client.mail.send.post(requestBody: mail.Get())).ConfigureAwait(false);

    // This line is never executed.
    return this.Ok();
}

I cannot use the client library at all until this is resolved. I'll be making "raw" HTTP requests instead using HttpClient.

[thinkingserious]

Thanks @matthewbcline!

What does the code look like that calls SendEmail()?

Seems like we need to have .ConfigureAwait(false); here and here.

[matthewbcline]

@thinkingserious SendEmail() is a Web API method; it's triggered by an HTTP POST. So it's called by the Web API routing framework.

I had a sneaking suspicion that the solution would involve ConfigureAwait(false). :wink:

[thinkingserious]

Agreed, I will try that fix and report back. Thanks!

[alanhouck]

@thinkingserious I was experimenting with the ConfigureAwait(false) earlier today and had no joy. Thankfully I checked this thread and tried adding it to the exact spots in the code you mentioned and it worked for me. Thanks!

[thinkingserious]

@alanhouck thanks for confirming!!!

I will push out an update and I'd like to swag out everyone on this thread. Please send your T-shirt size and mailing address to [email protected] :)

[thinkingserious]

This issue is fixed in version 7.0.2: https://github.com/sendgrid/sendgrid-csharp/releases/tag/v7.0.2

[joantorres]

@thinkingserious This worked!
Thanks a lot for the quick fix, and for the T-shirt ;-)

[PranKe01]

Now, which one is the correct call?

dynamic response = sendGridClient.client.mail.send.post(requestBody: mail.Get());
dynamic response = await sendGridClient.client.mail.send.post(requestBody: mail.Get());
dynamic response = await (sendGridClient.client.mail.send.post(requestBody: mail.Get())).ConfigureAwait(false);

[thinkingserious]

@PranKe01 whether or not you include the await keyword depends on your desired behavior, please see: https://msdn.microsoft.com/en-us/library/hh156528.aspx

[PranKe01]

When using dynamic response = await sendGridApi.client.mail.send.post(requestBody: mail.Get()); instead of dynamic response = sendGridApi.client.mail.send.post(requestBody: mail.Get()); I get an exception.

[thinkingserious]

@PranKe01 what is the exception you are receiving?

[PranKe01]

An exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in System.Web.Mvc.dll but was not handled in user code

Additional information: SendGrid.CSharp.HTTP.Client.Response enthält keine Definition für GetAwaiter.

[thinkingserious]

@PranKe01 do you mind creating a new ticket for that specific issue? If I don't hear back I'll go ahead and create it.

[mhagesfeld]

@thinkingserious - Not sure if this is related, but I have an issue where I built a library to send emails. Testing it, it works fine. If I take the code into my MVC project, it works fine. However, if I include the package in my MVC project and make the call to the library, I do not get a response. Any idea what might be happening? Should I open a separate issue?

Library code:

public async Task<string> SendEmail(string toAddresses, string fromEmailAddress, string fromName, string bccAddresses, string subject, string templateId, string bodyContent, Dictionary<string,string> substitutions)
{
 var message = new SendGridMessage();
            message.From = new EmailAddress(fromEmailAddress, name: string.IsNullOrEmpty(fromName) ? null : fromName);
            message.Subject = subject;
            if(!string.IsNullOrEmpty(templateId)) message.TemplateId = templateId;

            message.AddTos(GetEmailAddressListFromCommaSeparatedEmails(toAddresses));
            if(!string.IsNullOrEmpty(bccAddresses)) message.AddBccs(GetEmailAddressListFromCommaSeparatedEmails(bccAddresses));

            message.AddSubstitutions(substitutions);

            var client = new SendGridClient(apiKey);
            var response = await client.SendEmailAsync(message);
            return response.StatusCode.ToString();
}

MVC code:

        public async Task<string> SendValidationEmail(string toAddress, string code, Guid invitationId)
{
var verificationUrl = string.Format("{0}/account/verify/{1}", ConfigurationManager.AppSettings["SiteUrl"], invitationId.ToString());
            var substitutions = new Dictionary<string, string>
            {
                { "-verificationurl-", verificationUrl},
            {"-code-", code }
        };
            var result = sender.SendEmail(
                toAddresses: toAddress,
                fromEmailAddress: ConfigurationManager.AppSettings["FromEmail"],
                fromName: ConfigurationManager.AppSettings["FromName"],
                subject: "Your Calfee Connect Verification Code",
              templateId: "94bae6c6-2d25-47b2-9198-21215e76d4a9",
              bccAddresses: string.Empty,
              bodyContent: string.Empty,
              substitutions: substitutions
              ).Result;
return result;
}

[thinkingserious]

Hello @mhagesfeld,

Please do open a separate issue and we will investigate. Thanks!

[Korijn]

This is still an issue!

[thinkingserious]

Hi @Korijn,

Could you please provide further detail so that I may assist?

1. What version of the SDK are you using?
2. Sample code that is causing trouble?

Thanks!

With Best Regards,

Elmer

[tawani]

@thinkingserious
This is still an issue. SendEmailAsync is not responding (ASP.NET Web API C#). My app just hangs and no response is ever returned

It, however, works on my test Console app

Sendgrid v9.2.0
.NET Framework 4.6.1

var client = new SendGridClient(ApiKey);
var msg = new SendGridMessage()
{
    From = new EmailAddress("[email protected]", "MySite Team"),
    Subject = email.Subject,
    PlainTextContent = StripHtml(email.CreateMailMessage().Body),
    HtmlContent = email.CreateMailMessage().Body
};
msg.AddTo(new EmailAddress(email.To));

msg.SetFooterSetting(true,"MySite &copy; 2016", "<strong>MySite &copy; 2016</strong>");
msg.SetClickTracking(true, true);

var response = await client.SendEmailAsync(msg);
//response never gets returned

[Korijn]

The call to ConfigureAwait(false) that is made internally is messing up my program. SendGrid devs, why is that call there? If you could make the boolean a parameter so users can determine the value passed to ConfigureAwait, that would resolve the problem for me.

[thinkingserious]

Hi @tawani,

I will address this issue more fully shortly, but for now, please try this:

var response = await client.SendEmailAsync(msg).ConfigureAwait(false);

@Korijn,

I like the idea of making that configurable. As to why we did it, we had a long conversation about this, with reference to this article that ultimately resulted in this solution. I'll come back with further details later. I just jumped in real quick to hopefully solve @tawani's issue.

Thanks!

[thinkingserious]

@tawani,

Were you able to resolve the issue with my suggestion? As part of this issue we will be updating our examples to help avoid this type of issue in the future. Thanks again for your feedback!

@Korijn,

Here is the issue to implement a configurable ConfigureAwait. Thanks for the suggestion! Could you provide some reasoning on why we would want ConfigureAwait to be true? I'd like to add that to the issue. Thanks!

[tawani]

@thinkingserious
var response = await client.SendEmailAsync(msg).ConfigureAwait(false);
Did not work either.
No emails were sent and none of the emails even show up on my SendGrid dashboard

[thinkingserious]

Hello @tawani,

Can you share how you are calling SendValidationEmail?

Also, perhaps this example might help.

[tawani]

Not sure about SendValidationEmail

This is how I am calling the service:

var msg = MailHelper.CreateSingleEmail(from, to, email.Subject,
plainTextContent, htmlContent);
var response = await client.SendEmailAsync(msg).ConfigureAwait(false);

Please advice!

Hello @tawani,

I have tried to reproduce, but I am not getting any errors, the button gets updated with the string "Accepted" and the email gets delivered with the following code:

using System;
using SendGrid;
using SendGrid.Helpers.Mail;
using System.Threading.Tasks;

namespace TestingWebForms
{

    public partial class Default : System.Web.UI.Page
    {
        public void button1Clicked(object sender, EventArgs args)
        {
            var response = Execute().Result;
            Response result = response;
                        button1.Text = result.StatusCode.ToString();
        }

        public static async Task<Response> Execute()
        {
            var apiKey = Environment.GetEnvironmentVariable("SENDGRID_API_KEY");
            var client = new SendGridClient(apiKey);
            var from = new EmailAddress("[email protected]", "DX ");
            var subject = "Hello World from the SendGrid CSharp SDK!";
            var to = new EmailAddress("[email protected]", "Elmer Thomas");
            var plainTextContent = "Hello, Email!";
            var htmlContent = "<strong>Hello, Email!</strong>";
            var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
                        var response = await client.SendEmailAsync(msg);
            return response;
        }
    }
}

Please take a look and let me know what you think.

[tawani]

the button gets updated with the string "Accepted" Yeas. But the email
NEVER gets delivered. That is the problem.
My emails never get delivered. They don't even show up in my Sendgrid
dashboard.

Please advice!

Hi @tawani,

It sounds like something may be wrong with your account. Could you please reach out to our support team so that they can take a deeper look? Thanks!

[tawani]

I have already opened a tciket and contacted support since Sunday.
But they still have resolved anything.

Please advice!

Hi @tawani,

Did you try the solution offered regarding your lists?

[tawani]

Which solution? None works.
I have been manually resetting emails all day because Sendgrid is not working.

[thinkingserious]

The last one sent by our support team regarding certain emails on your lists, I believe it was sent on Saturday.

What do you mean by manually resetting emails? Do you mean resending?

Do you mind sending more of your source code so that we may try to reproduce?

[thinkingserious]

If you prefer not to post it here, please send to [email protected].

[tawani]

I have tried everything you sent. No email is delivered.
The only email that gets delivered is the one sent to "[email protected]"
(my own email address). Emails don't get delivered or even displayed on my
Sendgrid dashboard.

Please advice!

Hi @tawani,

    public void Send(Common.Emailing.Email email)

        SendAsync(email).Wait();
    }

Please try:

1. Uncomment return response
2. Replace SendAsync(email).Wait(); with

SendAsync(email).Result;
Response result = response;
var statusCode = result.StatusCode.ToString(); // log this value appropriately so that you can read the result

1. Replace public async Task SendAsync(Common.Emailing.Email email)
   with public static async Task<Response> SendAsync(Common.Emailing.Email email)

Also, when you say "The only email that gets delivered is the one sent to "[email protected]". Do you mean that when you try your code with that email it works fine, but when you try again with any other email it does not work? Could you try sending to [email protected]?

[tawani]

I used "[email protected]" and a bunch of other emails on a test Console
app. And only "[email protected]" was delivered.
See screenshot below - Only console apps get logged by Sendgrid:

Hi @tawani,

Did you try making the 3 changes I suggested?

Can you please walk me through step by step what happens when you have the result of "The process just sits there waiting forever"?

For example:

1. Using Visual Studio version X.X I create a XXXXX project
2. I use the following code:
   [Sample Code]
3. When I run the code and set a breakpoint at some point after the await client.SendEmailAsync(msg);, the breakpoint is never reached.

[tawani]

It never gets to the break point.

The code stops immediately after calling send email async (ie at var
response)

var response = await client.SendEmailAsync(msg);
return response;

Did you try making the 3 changes I suggested?

[thinkingserious]

Just before you call var response = await client.SendEmailAsync(msg);, can you tell me the output of msg.Serialize()?

[tawani]

Yes. Didn't you see my screen shot?

Your screen shot is not showing up here on GitHub. Perhaps you can upload it somewhere and provide the link.

Take a look at your personalization block:

  "personalizations": [
    {
      "to": [
        {
        }
      ]
    }
  ],

Your email is not getting added.

Can you take a look at msg.AddTo(new EmailAddress(email.To));, specifically, please verify the value of email.To. And for a quick test, you can manually add an email address there.

Thanks!

[tawani]

It seems our previous "Email" component is not adding the to email.

Verifying it.

Thanks!

Sounds good, please let us know how it goes. Thanks!

[tawani]

Our previous component was the SMTP MailMessage which contained the
"to/from/subject" information. That is why our Conole app was working but
not the web app.
I have updated the code and attached is the latest message.
It seems to have been processed but we still haven't gotten a response yet.

Thanks!

The emails are now going throw but the response still doesn't return.
For some reason also, my valid emails are getting dropped (see screen shot
attachment).

Any idea why?

Thanks!

@tawani,

I'm still not seeing any attachment. GitHub must scrub them from emails.

[tawani]

Sendgrid is still not returning a response even though the email is now
actually being sent.

Please advice!

Hello @tawani,

Unfortunately, I still do not see any attachment. Do you mind uploading to a service like Dropbox? So far, I'm unable to reproduce the issue.

Also, we have a new example that might help you.

With Best Regards,

Elmer
