trace_route/trace_attributes API fails to find nodes on motorways

[pmgomesLoL]

Hello,

I'm trying to use the Map Matching service API to snap a GPS route to the road network. Initialy I've used the demo server (https://valhalla1.openstreetmap.de) to check my bearings, afterwords I've setup valhalla-docker on my Ubuntu server 24.04 LTS. All the shapes that include a motorway are beeing split up into multiple shunks, but using the same input on the demo server I have a good and fully connected route.

If i try to route this input on my server:

{
    "shape": [{"lat": 40.965471,"lon": -8.619191},{"lat": 40.958505,"lon": -8.609175},{"lat": 40.909855,"lon": -8.60684},{"lat": 40.859305,"lon": -8.570744},{"lat": 40.802535,"lon": -8.557593},{"lat": 40.784044,"lon": -8.559904}],
    "costing": "auto", "shape_match": "walk_or_snap", "trace_options": { "gps_accuracy": 10, "search_radius": 10 }
}

It responds with:

{
    "error_code": 444,
    "error": "Map Match algorithm failed to find path: walk_or_snap algorithm failed to snap the shape points to the correct shape.",
    "status_code": 400,
    "status": "Bad Request"
}

and on the backend (docker logs) i get these messages:

Using the latest Portugal osm data extracts https://download.geofabrik.de/europe/portugal-latest.osm.pbf

While using the Demo server (https://valhalla1.openstreetmap.de)

I get the corret route.
