a new chat does NOT solve the issue.
but a new chat that begins with a greeting does solve it. (lol)

+1 It’s really flaky sometimes it works and on other windows it fails.
Really frustrating, blocking us, specially it feels like such minor issue.

67

Awesome. This workaround fixed the problem.

The same problem is happening again and again from time to time - 1 in 10 prompts @Colin

@Felipe_Mahlmeister Could you grab a Request ID from a working run and a non working run?

70

@Colin can we get this resolved ?

71

@NIPUN_SETHI Do you have a new Request ID? (text, no screenshot please :slight_smile:)

Hello Colin, how are you doing? It took me a while to reply because I was waiting for the issue to occur again, and the good news is that I haven’t had this problem in the last few days. I hope the issue has been resolved; if it happens again, I will come back with more information about the error, as requested. Thank you for your support. Thanks
