Grafana Datasource 'unexpected error happened'

May be this is the case:

Query REST API with JSON Plugin

The “Minified React error” usually means that you’re attempting to load a plugin in an unsupported Grafana version. The recent versions of JSON API require at least Grafana 7.3. Could you try with a more recent Grafana version and see if it persists? Otherwise, please submit an issue on the project page.
