Hi all, I'm running into a issue with RunGreatExpectationsValidation, hope you can help. When I run it directly 
flow.run()
it works fine. When I register the same flow to a local server and run it with a local prefect agent I get the following error.
Copy code
File "/home/prinsn/Code/prefect/repo/gima-prefect-cicd/.env/lib/python3.8/site-packages/cloudpickle/cloudpickle_fast.py", line 602, in dump
    return Pickler.dump(self, obj)
TypeError: 'NoneType' object is not callable
I' m using: ge api V3 prefect==0.15.13 great_expectations==0.14.5 Any pointers? =D

Hi @Niels Prins! Where are you storing your Great Expectations project? Is it on your local machine?
n
Yes, in my demo setup it is stored on my local machine. Tried it with the flow in the great_expections folder and with the flow on the same level
a
What type of storage are you using for your flow?
n
Currently running with the default, also tried Docker storage. Both times with the pickled option
Found this one in the community

Will check if this runs in my local server and than slowly upgrade it to the latest versions. For now I will call it a night =D
@alex woke up fresh this morning, switched the flow to a 'stored_as_script' flow and it worked straight out of the box =P Seems that the GreatExpectationObject can not be de-serialized or something?
thnxs for your help =D

I’m glad that you were able to get it working!
