Raise alert - Microsoft.Rest.HttpOperationException: Operation returned an invalid status code 'BadRequest'

Getting an error using the raise alert activity. Just moved modern folders but never tried it in classic folders. Exception is as below. It doesn’t seem to be the main other reported error of permissions on the robot role which I have checked and updated. Thanks in advance for any help! Our orchestrator instance is on premises.

20.10.2+Branch.master.
