'Create EE temp list' task fails

[ansiblejunky]

Summary

'Create EE temp list' task fails when running a playbook using this collection/role to extract info about current venvs on an existing Tower node. The regex_replace filter function used here causes the following error. I'm assuming this is a problem with using Ansible 2.9.x but this syntax should work in 2.9 because we typically run the playbook on Tower node, which has Ansible 2.9.

OS / ENVIRONMENT

Desired Behavior

It should work, but fails. So the workaround was simply to remove the regex_replace filter functions from that line and that seems to work enough to get the results. Not sure the intent for those regex functions.

Actual Behavior

see above
