Hello,
I have a page set-up to create a sendgrid email utilizing the sendgrid API.
I have my custom action set-up and when tested, it works, and I receive the email that I’m supposed to!
However, in the previewer when I test, I get a 400 error, and I really can’t figure out how to troubleshoot it. Does anyone have any ideas on how to troubleshoot this error? I can’t see anything obvious in the network tab on the console.
Thanks for any help!
