Right, seems the lib was severely outdated

jsonschema 2.6.0

My pleasure

Hi BoredBat47 , this happens only when you use the --foreground flag?
Is this the full error? What version of clearml-agent are you using? What OS are you on?

SmugDolphin23 That fixed the issue, thank you very much!

The error appears regardless of --foreground tag. This is not full stacktrace, I will provide it with the next message.
clearml 1.9.0
clearml-agent 1.5.1

Hi BoredBat47 ! What jsonschema version are you using?

Can you please update it to the latest version? pip install -U jsonschema
