Problem with Grafana Map Panel on Docker: Unable to load locations in JSON format

Would love to use the plugin, but in trying to set up a basic “Match metric name against key value from JSON record”, I can’t get past the error message:

Unable to load locations in JSON format from “”.

The response status was 0 error.
The content type was null.
The error name was "error".
The full error was "".

This is with running both InfluxDB and Grafana on Docker. I’ve tried both 0.8.1 and 0.9.0 versions of the plugin. From the grafana docker container itself I can run a curl to the same URL, so http access from grafana does not seem to be an issue.

Is this a newbie setup problem? Any clues or suggestions on how to debug/log the issue would be appreciated. Thanks in advance.

Well, no responses so far … but, ignoring the specific problem I was having, can anyone here offer any tips or suggestions on how to debug / log this issue? i.e. just turning on some logging for the plugin may be helpful? Thanks …

Hi Paul,

apologies for the very late answer.

In the meanwhile, we’ve been able to continue the development and recently released version 0.15.0. Maybe you can try again with this version?

Otherwise, when loading an external resource, you might run into “same origin policy” problems. Maybe you can open the JavaScript console of your Browser, watch for any error messages and share them back with us?

With kind regards,
