When running a flow on Prefect Cloud, I got an error "Clients have non-trivial state that is local and unpickleable" - how to solve it?

Problem: unpickleable object

@Tim_Enders: Getting this error on Prefect Cloud, but not locally. Clients have non-trivial state that is local and unpickleable. The load still seems to run OK, but it is marked as failure. How can I get rid of this error?

Solution: turn off checkpointing

@Kevin_Kho: That looks like you have a task that maybe returns a Client of some sort? Turn off checkpointing for that task

@Tim_Enders: I didn’t think the object was a client… but I will give that a try
