Sorry for bringing on so much work on you guys!
Just to make sure I understand, this fix would also mean the other create source options with Gorgias should work too, right? (I had tried the message one and it does the same error.)
Exactly — you found an existing bug and gave us an opportunity to improve these sources and others, for you and everyone else. So thank you 
And yes, the fix Andrew is going to work on is going to fix all of the Gorgias sources
Great! Hopefully it is working soon then.
Looks like the fix is in QA now so it should be out asap!
Great to hear! Thank you for your patience!
+1 — thanks for your patience and for flagging it to us, Josh. And thanks for the quick fix, Andrew!
Thank you both! Now to play with it till I understand it.
