Prefect Community

Hey,
Im getting this error when I run a new flow on Prefect cloud.
```Unexpected error: TypeError("cannot pickle '_thread.lock' object")```
I used  is_serializable before registering the flow and got True.
Any ideas on how to tackle this?
Thx

This is something like you are returning an object in a task that can’t be serialized. You can test using `cloudpickle.dumps(obj)` to test it. You can also turn off `checkpointing` with `checkpoint=False` in the task

Yeah I’m familiar with this error - just not sure if thats the case here.
Can I share some code privately so you can take another look?

oh.. I got the same error at my code for define the flow. Where can i adjust the 'checkpoint' parameter? <@U01QEJ9PP53>
