Unknown expression "pitch" in layers filter #1272
Comments
TileServer-GL now uses the maplibre-style-spec and MapLibre js / native. MapLibre was forked from the open source mapbox 1.x , so support to current mapbox 2.x+ spec is not 100% since they have been on diverged paths for several years since mapbox went closed source. For TileServer-GL and MapLibre, you might want to try maputnik My guess is the pitch expression was added to mapbox after the fork, so it likely isn't supported. For example, I saw this discussion recently ( maplibre/maplibre-gl-js#4207 ) |
I don’t know how to thank you, acalcutt 🙏🙏🙏 |
I found another online map style editor. It has more modern look than maplibre maputnik and can save your map style in your online profile. |
Edit: Going to move this to maplibre, landed here searching and realize this is better suited there. |
I created a new style using mapbox studio. After Importing mapbox style.json to tileserver-gl styles, and when i start the server i get this error:
[Unknown expression "pitch"](undefined: layers[35].filter[4][1][0]: Unknown expression "pitch". If you wanted a literal array, use ["literal", [...]].)
I noticed that server cannot pars the filter of mapbox in some layers. the layer with problem is:
{
"id": "tunnel-oneway-arrow-white",
"type": "symbol",
"metadata": {
"mapbox:featureComponent": "road-network",
"mapbox:group": "Road network, tunnels"
},
"source": "composite",
"source-layer": "road",
"minzoom": 16,
"filter": [
"all",
["==", ["get", "structure"], "tunnel"],
[
"match",
["get", "class"],
["motorway", "motorway_link", "trunk", "trunk_link"],
true,
false
],
["==", ["get", "oneway"], "true"],
[
"step",
["pitch"],
true,
50,
["<", ["distance-from-center"], 1],
60,
["<", ["distance-from-center"], 1.5],
70,
["<", ["distance-from-center"], 2]
]
],
"layout": {
"symbol-placement": "line",
"icon-image": [
"step",
["zoom"],
"oneway-white-small",
18,
"oneway-white-large"
],
"symbol-spacing": 200,
"icon-rotation-alignment": "map",
"icon-allow-overlap": true,
"icon-ignore-placement": true
},
"paint": {}
}
when I remove the ["pitch"] fitler from the style.json, server error get vanish.
If I can help in any part of this problem and create pull request, please tell me. Thank you very much
