Hi @Speey

  1. Latest release is
  2. Migrate away from H2 if you’re using Metabase in production:
  3. Post errors - either from Admin > Troubleshooting > Logs - or from your browser console.

Thanks for this information :slight_smile:
Right now I try to create a new map, but I have issues finding a good one of Europe.
The page mentioned is fine, but then I need to install a WebServer, where I can provide this map-geojson, since I think it will not be cached anywhere on the Metabase-Node, right?

With “mentioned page” to load some geojson I mean http://geojson.io

@Speey Please read this: https://www.metabase.com/learn/basics/visualizing-data/maps.html

The website geojson.io doesn’t offer direct linking. You need to link to a GeoJSON file.

Here’s a map of Europe. I did a search on https://www.google.com/search?q=geojson+europe
Click the Download-button on the page and copy the URL into Metabase.

Wou … great … I was also searching and landed at SwissPost - no success.
Finally, I got always an error-msg while loading a map like … not iteratable.

At the end it was because the REFRESH-button wasn’t working.

Thanks for the help, i really appreciate :slight_smile:

SwissPost, because I need a map of Europe and a map of Switzerland.
