URL using bad/illegal format or missing URL: URL rejected: No host part in the URL

[SVH-Powel]

Hi. I am just looking at maplibre-native to see if it is usable for us. I have compiled the source and the example map provided in the documentation works. But I wanted to test mbgl-render on another map source, but I am not able to get it to work.

This is the command in Windows:
mbgl-render --style https://vector.services.geodataonline.no/arcgis/rest/services/GeocacheVector/GeocacheNordenGraatone_WM/VectorTileServer/resources/styles/root.json --zoom 10 --lat 60 --lon 10 --output geo.png

And this is the output:

[INFO] {}[Style]: Style '' has 2158 layers:
  None: 1781
  Zoom: 377

Does anyone here know why I get errors? Is the map source not in a compatible format. The owner of the map tell me that it is mapbox compatible. Is it an error in the maplibre-native render program or is it me who is using it wrong?

All URLs in a TileJSON endpoint need to be absolute.

I have heard a rumour that ArcGIS strategically almost but not quite implements TileJSON just to steer people towards their propietary solutions.

In any case, should be an easy fix, just make sure the all TileJSON URLs are absolue. You can host it yourself somewhere (or as a GitHub Gist).

Or you can just drop the url here. In general you want to choose between a TileJSON url or a tiles array... Having both is not common.

@SVH-Powel I vibe coded a URL rewriter to make ArcGIS style JSON /TileJSON spec compliant.

Try this style: https://arcgis-tilejson-rewriter.bart-louwers.workers.dev?style=https://vector.services.geodataonline.no/arcgis/rest/services/GeocacheVector/GeocacheNordenGraatone_WM/VectorTileServer/resources/styles/root.json

Nice map!

Thanks, @louwers :-)
