Overview

You may see the following error message from the path-filtering Orb's Set parameters step:

ERROR: This script does not work on Python 3.8. The minimum supported Python version is 3.9. Please use https://bootstrap.pypa. io/pip/3.8/get-pip.py instead.

Solution

Upgrade to version 1.3.0 of the path-filtering Orb which now defaults to Python version 3.9

OR
You may specify a custom image tag parameter, eg) tag: "3.9" to the path-filtering/filter job:

workflows:
  filter-and-continue:
    jobs:
      - path-filtering/filter:
          tag: "3.9"
          ...
