this is my yaml file, i want to load the custom models which are in the same directory as the yaml file

this error is popping up:

Can you try to specify the custom model directory?

custom_models.directory: ./

sankhyayan_chaudhuri · September 3, 2025, 8:49pm

i tried that, also looked up in gemini, i feel the issue is in the custom model itself, lemme share it with you, plej helppp meee

chandigarh_avoid_traffic.json (2.5 KB)

chandigarh_balanced.json (2.5 KB)

chandigarh_fast.json (2.7 KB)

heres my new config:

graphhopper:

# OSM data file for Chandigarh
