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?

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

I didn't think the object was a client.... but I will give that a try
