At this stage, the errors are coming to the frontend without any message printed:

We got the reason in the backend logs:

grafana-quickwit-datasource  | logger=context userId=1 orgId=1 uname=admin t=2023-11-24T12:01:01.010635245Z level=error msg="Internal server error" error="[plugin.downstreamError] failed to query data: Failed to query data: rpc error: code = Unknown desc = Error on multisearch: statusCode = 400, responseBody = {}, queryParam = \"max_concurrent_shard_requests=256\", requestBody = [{\"query\":{\"bool\":{\"filter\":{\"range\":{\"timestamp\":{\"gte\":\"2023-11-22T12:01:00.57Z\",\"lte\":\"2023-11-24T12:01:00.57Z\"}}}}},\"size\":100,\"sort\":[{\"timestamp\":{\"order\":\"desc\"}},{\"_doc\":{\"order\":\"desc\"}}]}]" remote_addr=192.168.247.1 traceID=

Still work in progress...

At this stage, the errors are accessible with the browser JS console and the http code from quickwit is propagated:

At this stage, using :

"github.com/grafana/grafana-plugin-sdk-go/experimental/errorsource"
// ...
response := backend.NewQueryDataResponse()
return errorsource.AddErrorToResponse(e.dataQueries[0].RefID, response, err), nil

We got a 200 response with empty body:

Whereas the error is still logged on the server side:

grafana-quickwit-datasource  | logger=plugin.quickwit-quickwit-datasource t=2023-11-27T14:57:18.449939435Z level=error msg="Error on multisearch: statusCode = 400, responseBody = {}, queryParam = \"max_concurrent_shard_requests=256\", requestBody = [{\"query\":{\"bool\":{\"filter\":{\"range\":{\"timestamp\":{\"gte\":\"2023-11-27T02:57:17.995Z\",\"lte\":\"2023-11-27T14:57:17.995Z\"}}}}},\"size\":100,\"sort\":[{\"timestamp\":{\"order\":\"desc\"}},{\"_doc\":{\"order\":\"desc\"}}]}]"
