I am running Elastic Stack 7.9 and am having issues with my dashboard. When I try to catch all my data (search for last 1000 years) in my Kibana dashboard I get an error on the saved Discover table that I have included, but not for the visualizations. In the console for the developer tools I see an error
Failed to load resource: the server responded with a status of 400 (Bad Request), when I look into the logs I see that the request is for
POST /internal/search/es but there is no further information.
It appears to work when I do the same in Discover, so what might be the cause of this error? I cannot access the elasticsearch logs at the moment. I have some formatter plugins active, such as converting some links to image previews. Could it be that the processing of the plugins and the huge amount of data is causing a server overload or something?
Why would this error only occur within a dashboard though, and not in Discover? Is the Discover Table in the Dashboard retrieving more data, or in a different way, than in Discover, for the exact same request (no filters, time 1000years - now)?
