In general, OpenSearch Dashboards requires OpenSearch to be available, and make requests. From the dashboards side, we'd be interested in better handling and communicating the errors from the cluster. Can you provide some example screenshots of the UI?

Triage: We need further research to identify where the request error handling failed.
