Here is the error as a txt doc

Hi @Zach - this is a fairly old version of Prefect, so lots could have changed in the dependency tree, but based on your traceback here it appears that you need to upper bound your dask dependencies

Hi @Zach Looks like you may need to pin the versions of

dask[bag]

and

distributed

. Also, considering updating to the latest version of prefect

cloudpickle<1.5,>=0.6.0 (from prefect==0.10.7->-r /tmp/pipenvaum751h_requirements/pipenv-i945vxae-constraints.txt (line 4))
  cloudpickle>=0.2.2 (from dask[bag]==2.25.0->prefect==0.10.7->-r /tmp/pipenvaum751h_requirements/pipenv-i945vxae-constraints.txt (line 4))
  cloudpickle>=1.5.0 (from distributed==2.25.0->prefect==0.10.7->-r /tmp/pipenvaum751h_requirements/pipenv-i945vxae-constraints.txt (line 4))

Updating to a more recent version of prefect fixed it! thank you @Chris White @Dylan

Nice!
