Sendgrid-csharp: Same code one calling from .net Console app and other from .net Web Api and web api fails

[fireole]

Web Api Method (Fails)

Console Method (Success)

• sendgrid-csharp Version: the latest 9.0.12
• .NET Version: 4.6

The Console sends the template email.
The Web API returns Status Code Bad Request and the in the Headers a DENY

I used the same api key, template id, and msg params.

Am I totally missing something?

Hi @fireole,

Could you please tell me the error message? You can grab it like this:

Console.WriteLine(response.Body.ReadAsStringAsync().Result);

Thanks!

[fireole]

so the console app works, but in the web api does not.

so I did this in the web api and captured a screenshot

you can see it comes back as BadRequest.

I also put this line in

var test = response.Body.ReadAsStringAsync().Result;

and got this:

{"errors":[{"message":"The content value must be a string at least one character in length.","field":"content.0.value","help":"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.content.value"}]}

does this help?

[fireole]

got it.

So I was using a template and not really sending any body text for .AddContact(). So I added this line

mailDto.Body = "test" which will fill the msg.AddContent(MimeType.Text, mailDto.Body);

and then it worked.

the msg.AddContent is mandatory whether you use it or not.

Hello @fireole,

After digging a little deeper, I found that we have not considered the case when you pass an empty string to the Content helper when using a template. We will update the SDK to handle this situation. You can follow that progress here: https://github.com/sendgrid/sendgrid-csharp/issues/419

If you do not have any content you wish to pass, then you do not need to call the msg.AddContent method.

With Best Regards,
