Error when adding source

[whbruce]

New to grafana, so this may be a rookie question. I see 4 entries for the MQTT data source in the configuration view (default, 1, 2 and 3).

I built mqtt-datasource but got the following error in grafana when I tried to add it. No obvious grafana logs to share.
Running on Ubuntu 20.04, not using a container. Grafana v7.0.

An unexpected error happened

@whbruce do you want to maybe try with Grafana v8.0?

for a streaming backend datasource plugin like this one a pre-requisite is Grafana v8.0+. see: https://grafana.com/tutorials/build-a-streaming-data-source-plugin/

will add this to the docs 😬

Thanks updating to v8.0 fixed it.
