Cannot read property '0' of undefined when loading a GTFS file

[denishuvelle]

Hello,

I tried to load this GTFS: http://opendata.tec-wl.be/Current%20GTFS/TEC-GTFS.zip

With this config:

{ "mongoUrl": "mongodb://localhost:27017/gtfs", "agencies": [ { "agency_key": "L", "path": "TEC-GTFS_cleaned_trips.zip" } ], "includeStops": false, "outputType": "route", "coordinatePrecision": 5, "zipOutput": false }

With this command: gtfs-to-geojson --configPath config.json --max-old-space-size=8000

It imports everything in DB but ends with an error in the GeoJSON creation:

`Starting GTFS import for 1 file(node:73204) DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.

I tried to isolate one route and all the corresponding trips (I removed all the other lines in these 2 text files) and it was running well... But I have no idea of which property is undefined.

Any idea on the issue? :)

Thanks for reporting this issue.

I pushed an update https://github.com/BlinkTagInc/gtfs-to-geojson/releases/tag/0.5.3 which should solve this issue.

Try it out and reopen this github issue if it still persists.
