Grafana is not able to get Prometheus metrics although Prometheus Datasource is validated successfully

Question

I am trying to configure Grafana to visulaize metrics collected by Prometheus. My Prometheus Datasource is validated successfully. But when I am trying to create dashboard then it's showing error saying "can not read property 'result' of undefined"

I am adding screenshots.

It looks like you are pointing towards the node exporter endpoint and not Prometheus Server. The default Prometheus Server endpoint is 9090. Try change your source to http://192.168.33.22:9090

Grafana doesn't query Node Exporter directly, it queries Prometheus Server which gathers the time series statistics.
