Unexpected errors while sending large attachment
Unexpected error when sending attachments larger than the limit of 15MB in a transactional email.
I would expect the mailjet client to return a send error like mj-0011 (.. the payload size is over the limit), but instead I get a MailjetClientCommunicationException with Caused by: okhttp3.internal.http2.ConnectionShutdownException.
Is this expected behavior? If so, when is the mj-0011 error used?
If I use latest version of okhttp (4.9.3), I get cause okhttp3.internal.http2.StreamResetException: stream was reset: CANCEL.
@Kristianrosland, thank you for raising this issue. Yes, the total email message size must not exceed 15MB. https://dev.mailjet.com/email/reference/send-emails/#:~:text=The%20total%20size%20of%20attachments,should%20not%20exceed%2015%20MB.

When I've tried to use the latest okhttp-client 5.0.0-alpha.10, the error looks more readable
<html><body><h1>413 Request Entity Too Large</h1></body></html>
The okhttp-client will be updated once 5.0 is released.
When hit the API from Postman, got the same error:
<html>
<body>
<h1>413 Request Entity Too Large</h1>
</body>
</html>
If so, please ask Mailjet Support about mj-0011 error.
