Getting warning message in logs with error message ErrorMessage@b16ceeed

Summary

There are some warning message in log file regarding Service Desk Automation even if there is no automation rule was set. The error message is not good enough to narrow down to any root cause of the warning message.

Steps to Reproduce

1. Installed Service Desk.
2. Create a Service Desk project.
3. Delete all the automation rule.
4. Observe the atlassian-jira.log for the warning message with error message; "ErrorMessage@b16ceeed".
5. To check if there is any automation rule that is active, you can run the following SQL:

   select * from "AO_9B2E3B_RULESET";
   

   Sample output for no active automation rule:

   -[ RECORD 1 ]------+--
   ACTIVE_REVISION_ID |
   ID                 | 1
   -[ RECORD 2 ]------+--
   ACTIVE_REVISION_ID |
   ID                 | 2
   

   Sample output for an active automation rule:

   -[ RECORD 1 ]------+--
   ACTIVE_REVISION_ID |
   ID                 | 1
   -[ RECORD 2 ]------+--
   ACTIVE_REVISION_ID |
   ID                 | 2
   -[ RECORD 3 ]------+--
   ACTIVE_REVISION_ID | 3
   ID                 | 3
