SendGrid demands categories to be set

[robertjf]

When we upgraded to the latest release, our emails stopped sending via SendGrid with the following error in the response:

"{\r\n  \"message\": \"The categories array, when used, must have at least one category.\",\r\n  \"field\": \"categories\",\r\n  \"help\": \"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.categories\"\r\n}"

Installed version: 3.0.2

Workaround seems to be to set the .Tag property to some string.

We just hit this same issue with SendGrid e-mails failing to send after updating.

Issue still exists and the ☝️ workaround works

So apparently I had the same issue, the initial call was :

 var sendResponse = await _fluentEmail
                    .To(email)
                    .Subject(mailTitle)
                    .Body(body, true)
                    .Tag("string")
                    .SendAsync();

which resulted in sending only the first email in a Foreach loop, so I had to replace it to :

 var sendResponse = await _fluentEmail
                    .To(email)
                    .Subject(mailTitle)
                    .Body(body, true)
                    .Tag($"{GenerateUnique()}")
                    .SendAsync();

to be able to work around this issue.

I think a fix for this has already sneaked into master via this PR. So just a release away 😉

Okay.... this is still not yet realease

Thanks @jazzmanro for the work-around. Seems the PR is merged but not released. I guess @lukencode is buried in his full-time role as dad and CTO (understandable). Does anyone else have release authority? @bjcull? 🙏

I can't release anything on this repo, but I made a fork and integrated a bunch of the open PRs and made my own release:
