[Qgis-user] How to apply own styles to custom vector tiles?

[Rahkonen Jukka (MML)]

Hi,

I can add vector tiles into QGIS 3.14 from the WMTS service of the National Land Survey of Finland with the following URL (api-key will change some day)
https://avoin-karttakuva.maanmittauslaitos.fi/vectortiles/taustakartta/wmts/1.0.0/taustakartta/default/v20/WGS84_Pseudo-Mercator/{z}/{y}/{x}.pbf?api-key=1858323a-ea54-4815-be07-fbecc99dcfd5<https://avoin-karttakuva.maanmittauslaitos.fi/vectortiles/taustakartta/wmts/1.0.0/taustakartta/default/v20/WGS84_Pseudo-Mercator/%7bz%7d/%7by%7d/%7bx%7d.pbf?api-key=1858323a-ea54-4815-be07-fbecc99dcfd5>
"Zoom to layer" shows just one point but just zoom in and map looks a bit like a map.

But how could I apply or convert the Mapbox GL styles from URL to be used in QGIS? The style file is available at
https://avoin-karttakuva.maanmittauslaitos.fi/vectortiles/stylejson/v20/backgroundmap.json?TileMatrixSet=WGS84_Pseudo-Mercator&api-key=1858323a-ea54-4815-be07-fbecc99dcfd5
The style file works well in Maputnik.

I installed the Maptiler plugin but I did not discover if it can be used for importing styles written for custom vector tiles or if it is somehow tied to vector tiles delivered by Maptiler. My trials yield just Python errors like this

Traceback (most recent call last):

              lambda: self._add_custom_to_canvas())

              if self._is_vector_json(json_url):

              data_format = json_data['format']
             KeyError: 'format'
