When creating an alarm policy using a regex statement and attempting to save it. We receive a "failure executing action - Request failed with Status code 500).
Regex is longer than 256 characters.
Release : 20.3
Component : UIM - OPERATOR CONSOLE
This regex field is designed with a limit of 256 characters. Anything over that will generate this error. You can break the longer regex filter into smaller strings to use in other conditions of the same policy.
This issue is reported as resolved in UIM 20.3.3.
