CORS and localhost datasource

[rizahmed77]

Hi @simPod
In Grafana 7.x, I was able to use your plugin for json endpoints on my localhost (using Browser) and this was helping me develop and debug data sources locally.

Since I upgraded to Grafana 8.x and your plugin to 0.3.0, calls to localhost don't work anymore. The request fails with a console error "net::ERR_FAILED".

It does not seem to be CORS issue as I can use non-localhost sources without issue. Also, my localhost source continues to work fine in your plugin in Grafana 7.x.

Do you think this is something related to Grafana 8.x or your plugin?

Thanks

Can't help much here, "net::ERR_FAILED" can be anything.

Did you check release notes on v0.3?
