Hello, I received the above error message when I tried to use this tool. I don't think it's an issue with my GTFS data, since a year ago I used this tool last year in v.2.8 when it was called "GTFS To Network Dataset Transit Sources tool" and it worked fine. With the same dataset I still received the same error. I see the stops feature class loaded correctly, but for LineVariantElements nothing shows up, and when I tried to open the tables (CalendarExceptions, Calendars, Lines, LineVariants, Runs, ScheduleElements, Schedules), it says "Failed to open table". How can I resolve it?
Thanks in advance!
UPDATE: This is resolved, turns out it was because I was working on a Network Drive, I changed it to local and everything is running fine 🙂
