Top three things to fix
Add the required column named in the finding to the flagged file.
A file is missing a column that GTFS requires. Apps may reject the whole file, so riders could lose the affected routes or stops.
Effort: Often an export setting; ask your vendor if it recurs.
Review the rule documentation for 'invalid_row_length' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Invalid row length (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
2027 of 2027 stops don't say whether a wheelchair user can board there. Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.
Effort: A column in stops.txt; your scheduling software likely has it.
