Running "Hello Email" sample code gets a 400 error response from the API about sendgrid-ruby

[safetymonkey]

Alright, I figured it out. It's an embarrassing "LRN 2 code n00b" moment. Mail.new is being hijacked in Rails by ActionMailer. Instead of trying to figure out how to hand that back to the Sendgrid gem I can just specify SendGrid::Mail.new and that does the trick.

Sorry for the dumb question. I'll resolve the issue.

[thinkingserious]

Not dumb at all, and it's greatly appreciated that you took the time to share the solution. I'm sure you'll help someone who is having a similar issue in the future.

Hello, n00b here. :) Had a similar issue in my production environment (but worked fine in dev), this thread helped me a lot. So just confirming "you'll help someone who is having a similar issue in the future". Thanks a lot @safetymonkey.

[christianroy]

Oh don't worry @safetymonkey, I solved my problem by specifying SendGrid::Mail.new like you did. I was just thanking you for your documentation efforts back in June...

[safetymonkey]

Ah. I'm glad it helped!

[itsameandrea]

@safetymonkey - thanks a lot for your help! You saved me a lot of troubleshooting :)

[senyoAsamoah]

@safetymonkey - thanks a lot, run into similar issue implementing sendgrid on my local dev and coming across his thread and your solution helped

Was creating a rake task to test the mailer, which gave the same error. Fixed it with adding the SendGrid:: before all the lines with New. Thanks @safetymonkey!

Hello @safetymonkey,

Could you please let me know what the return value of mail.to_json is? Thanks!

Interestingly, I was able to get the code to succeed in IRB but not in the Rails console. I suppose this points to a problem with my environment setup but the error message returned from the API was frustratingly vague.

[safetymonkey]

It looks like there is something in the Rails console that is conflicting with Sendgrid that isn't happening in IRB. In the console the mail.class is Mail::Message and in IRB it's SendGrid::Mail.

This looks like a local setup issue so feel free to resolve, although if you have any helpful ideas I'd be all ears

[safetymonkey]

I'm happy to try and help if you can provide more info on exactly what you're seeing.

[VictorAcatrinei]

Would this fix be something that can be added to the documentation or in some place that can be visible for even more people?

[thinkingserious]

Great idea @VictorAcatrinei,

We will get it added to the TROUBLESHOOTING.md document.

[thedanotto]

@safetymonkey never woulda figured it out with you!!! Can't believe this hasn't been updated in their documentation

[thinkingserious]

Hi @thedanotto!

Thanks for following up with some feedback!

If you don't mind, to help us improve, could you share the places you looked before you arrived here?

With Best Regards,

Elmer
