I encountered this after installing a script when I attempted to add a schedule. The system throws an error when trying to display the groups panel to allow choosing which group to run the script against. I'm asking if anyone has encountered this and was able to resolve it.
Also looking for suggestions on which logs to review to chase this down.

The schedule WAS assigned to the script and the script did run against the global group - but I would have no way of running it against a subgroup.
