Moving this from another thread since it was unrelated to the original. I registered a new version of a flow this morning that started failing with
Copy code
Failed to retrieve task state with error: ClientError([{'path': ['get_or_create_task_run_info'], 'message': 'Expected type UUID!, found ""; Could not parse UUID: ', 'extensions': {'code': 'INTERNAL_SERVER_ERROR', 'exception': {'message': 'Expected type UUID!, found ""; Could not parse UUID: ', 'locations': [{'line': 2, 'column': 101}], 'path': None}}}])
@Mason Menges Pointed me to https://discourse.prefect.io/t/how-to-fix-the-error-prefect-exceptions-clienterror-message-expected-type-uuid-found-could-not-parse-uuid/832 to assist. I ended up having to register the flow 3 times for it to start working. The first registration was the only time there were changes to the flow, I had to register an additional two times with zero changes to get the error to stop. Is there an issue related to this article or anything that can be done to dig into what exactly is going on?

It looks like we have had discussions around this in the past on this issue https://github.com/PrefectHQ/prefect/issues/5075 it's not something that appears to occur frequently there are some ideas of what might be related to it.

Thanks, I added a comment mentioning I have seen the same issue; however, the issue is already closed as non-producable.

Hey @Kevin Mullins would you be willing to provide some flow ids so we can look into this a bit more? feel free to dm them to me if you're ok with that 🙂
