Hi!
I am using the latest version of GraphHopper with multiple countries merged in one OSM file and multiple GTFS files for public transport: everything is working perfectly for routing but I have an issue with the isochrone API.
Calculate an isochrone for car or bike is running file but it’s not the case if I used the profile “pt”, I always get this error in the logs:

I tried to search for this specific error but I can’t find anything 
Any idea of what is going on?
