Sendgrid-php: Handling errors

[jaimehing]

How do I handle the errors in sending emails? I've tried to wrap the calling function with try catch but it is still printing the json error: e.g.

[
{
"message": "Each email address in the personalization block should be unique between to, cc, and bcc. We found the first duplicate instance of [[email protected]] in the personalizations.0.cc field.",
"field": "personalizations.0",
"help": "http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.recipient-errors"
}
]

I don't want the library to print these errors instead I'd like to handle it.

I also are having an issue handling these, I would like to catch these errors and be able to return the error message to our logging systems.

Hello @jaimehing, @KnightAR,

try {
    $response = $sendgrid->client->mail()->send()->post($mail);
} catch (Exception $e) {
    // Handle Exception
}

Does that help?

Hi @thinkingserious. nope. that's the thing I've tried and it's being forced to return the error json response

Hi @jaimehing,

I'm not sure what you mean by "being forced to return the error json". Can you please provide some code to help provide some context?

Thanks!

@thinkingserious When CURL occurs a 400 error message, it does not return the body and sends the body to STDERR instead. The work around would be to set a HTTP 200 Alias to 400 and set CURLOPT_FAILONERROR to false. However, I couldn't get it working.

@KnightAR,

Ah, thanks! Looks like we will need to make the adjustment here: https://github.com/sendgrid/php-http-client/blob/master/lib/Client.php#L144

I'm classifying this as a bug and putting it on our backlog for a fix.

@jaimehing @thinkingserious With the recent update, I got it working by doing the following:

$sg = new \SendGrid($sendgridkey, [], array(
    CURLOPT_FAILONERROR => false,
    CURLOPT_HTTP200ALIASES => [400],
    CURLOPT_VERBOSE => false
));

var_dump(json_decode($response->body()));

As a test, I did an invalid request and got a propery json body:

  public $errors =>

@KnightAR,

Thanks for circling back with the solution! Please fill out this form and we will send you some swag.

@KnightAR What recent update are you talking about ? Sendgrid constructor (master or tags) doesn't have a third parameter.

public function __construct($apiKey, $options = array())
