Is there a way to change these error messages to something like "No results found"?
I am afraid not. Could you elaborate why would you want that? This error is different than "no results found". It specificallt points to one of the fields not being found
I want to import Kibana dashboards with widgets and data views. This error keeps showing until I populate Elasticsearch index with data (I'm aware that the index is not created when this error is showing). I want to create a pleasant view until the index is created with data. Any help would be highly appreciated.
We are working on this as we speak, it should be released as part of 8.3.0 version.
