Hi,
I get the following error in Kibana (8.4.3) when trying to view an alert. It appears that this is causing alerts not to fire at all. Everything was working fine about a week ago. I've already tried creating a new alert but get the same error. Any ideas on how I can resolve this?
Failed to fetch execution history
An internal server error occurred. Check Kibana server logs for details.
