My first time with GTFS routing, so no clue what I’m doing wrong. I use a GTFS file from this site and an Estonian OSM file. I tried to set up the routing according to instructions and got it to build properly, but when I try to set up the routing I get the following problem:

How should I proceed? Is the file the problem?
