Looks like an exception on the backend of your data source. Is that your own custom data source?

Hi daniellee,

I copied a custom simple-json data source on the local grafana path:
C:\Grafana\grafana-4.4.1\public\app\plugins\datasource\simple-json-datasource
and also to: C:\Grafana\grafana-4.4.1\data\plugins\simple-json-datasource

another package “dmms-grafana-copy” has been deployed on the remote server (XSA Hana Server) where grafana is connected to. Two apps have been created with an https address and a port.
I put the url address on the grafana datasourse configuration.
The connection is working!
The dashboard is not working :frowning:

Really hard to say what the problem is as these are custom plugins with custom code. It looks like a bug in your data source or in "dmms-grafana-copy”. Did you write the plugin/backend for XSA Hana Server? If not, then maybe the author of the plugin or backend can help you?
