I don't think this is the answer you were looking for but you asked a YES/NO question and you didn't give enough information to say more 😄 could you perhaps explain when/how did you encounter this error? what flow did you run? was it with the latest version?
and please could you move the code block into the thread to keep the main channel clean? Thanks in advance!

Pending log batch size: 0thank you. I have posted this error hoping that maybe it is something known 😉
I will try to provide more details today
It is prefect2.0 (2.0b7)
I rerun the same flow again and now it finished without errors 😕
From the above logs I would suspect that it was some problem in prefect's logging mechanism, but maybe not...
Yesterday I got this error but Flows/Tasks succeeded, so it is not something very harmful
I will try to reproduce it but I don't know if I will be able to...
