When using the grafana API datasource health check against a datasource using the victoriametrics-datasource plugin, e.g. using /api/datasources/uid/abcdefghijklmn/health then it fails with a 400 status and a JSON body
The datasource is configured with the URL http://vmselect-aggregator-clusterip.vm-output.svc.cluster.local:8481/select/1234/prometheus (note the multitenant setup) and otherwise works fine, only the above health check does not work.

http://vmselect-aggregator-clusterip.vm-output.svc.cluster.local:8481/select/1234/prometheus(note the multitenant setup) and otherwise works fine, only the above health check does not work.If I understand the source code correctly, then the health check is done in this function https://github.com/VictoriaMetrics/victorialogs-datasource/blob/518eca5756fbab962a54f42420e0326dd7f3a6c0/pkg/plugin/datasource.go#L146 The
/healthpart is just added to the configured URL, so the result would behttp://vmselect-aggregator-clusterip.vm-output.svc.cluster.local:8481/select/1234/prometheus/healthwhich does not work (i.e. fails with a 400, which is then propagated).
