"Unable to compute isochrone total_pop attribute" error while creating isochrones

Hi.

I’m trying to create some isochrones from a point layer On Qgis 3.40.4-Bratislava.

It works for pedestrians, but not for driving-car.

Here’s the message I get:

Feature ID 87594739 caused a GenericServerError:
500 ({“error”:{“code”:3099,“message”:“Unable to compute isochrone total_pop attribute.”},“info”:{“engine”:{“build_date”:“2025-06-06T15:39:25Z”,“graph_version”:“2”,“graph_date”:“2025-10-26T11:34:55Z”,“osm_date”:“2025-10-20T00:00:01Z”,“version”:“9.3.0”},“timestamp”:1761668871772}})

Anything I can do ?

thanks for bringing this up. We are looking into it and will let you know once it is resolved.

Best regards
