#2884 [BUG] Getting started guide, can't run on local cluster Issue created by tamis-laan Describe the bug I'm trying out Flyte locally running through the getting started guide: https://docs.flyte.org/en/latest/getting_started/index.html The code runs great using

pyflyte

but doesn't work properly when running on the local demo cluster. running:

> pyflyte run --remote example.py wf --n 500 --mean 42 --sigma 2

results in the error:
