Previously, if a Predefined condition had a unique ID containing a dash (e.g. "my-condition"), creating or editing any rule crashed with an error similar to:

Internal error: 'my-condition' is not a valid, non-reserved Python identifier

This affected all rules, not just the one using the predefined condition. This change fixes that behavior and now dash containing predefined rules unique ID are allowed
