While using a index pattern in kibana and
Use 30 day filter
Kibana gives request to elasticsearch failed.
Request to Elasticsearch failed: {"error":{}}
How to solve this problem
@Dragon9 Do you have a stack trace you could provide, and perhaps a screenshot of your browser console?
I'd also recommend looking in your browser's network requests panel -- the response data from the search request may contain more info that isn't being surfaced in the UI.
