We have made a dashboard, with graphs which was using a datasource named X (influxdb database X) .
After that , we have created a new datasource Y (influxdb database Y) and change X by Y in all panels
All graphs works but each time we choose this dashboard, we have an error popup “templating init failed, datasource named X was not found”.
i have exported the dashboard to json to see old datasource references, but there is nothing.
how to find the root cause?
