Issue with Task Scheduler Propagation - Task Path GitHub script

I was attempting to use PAM for rotating passwords in a Windows Scheduled Task, and I was running into an error with the path to the scheduled task:

Propagation: Error
Error while executing the script Scheduled Task with the configuration Test Schedule: Cannot validate argument on parameter 'ScheduledTaskPath'. The argument "\" does not match the "^\\(?:[^\\]+\\)+\s*(?:,\s*\\(?:[^\\]+\\)+)*$" pattern. Supply an argument that matches "^\\(?:[^\\]+\\)+\s*(?:,\s*\\(?:[^\\]+\\)+)*$" and try the command again.

My task was at the root level:
TaskPath TaskName State
-------- -------- -----
\ CMD Running


This pattern does not allow the use of the root of scheduled tasks: [ValidatePattern('^\\(?:[^\\]+\\)+\s*(?:,\s*\\(?:[^\\]+\\)+)*$')]
I updated my local copy of the script to use this instead: [ValidatePattern('^(\\|(?:[^\\]+\\)+\s*(?:,\s*\\(?:[^\\]+\\)+)*)$')]

This seems to have worked.
