Hello everybody. I’m running a local agent inside a docker container and triggering a flow from Prefect Cloud and getting this stacktrace:

However, I can run it locally using flow.run() without issue. I can see in the code that environment is not set, but I don’t understand what I’m doing wrong… Thanks in advance!
Hi Robert - this appears to be a situation where your agent has an older version of Prefect, and your Flow is using a newer version. For Local Agents we recommend keeping those versions in sync — if you upgrade your agent I believe this will go away
@Chris White Thanks, I re-registered my flow with Prefect Cloud and the version listed in the UI changed from 0.13.x to 0.14.2 and now it works. My local prefect is also 0.14.2 so now I know. Thanks!
Anytime - glad I could help!
