Hey @richfab could you provide more context/details about this task?

[emmambd]

Hey @qcdyx - you can get context from other people on the dev team. cc @davidgamez can maybe show you how to trigger a new release for the GBFS validator to use the new schema.

[qcdyx]

Thanks, @emmambd! We should also document the process to make it easier next time.

[richfab]

I agree that documentation about this process would be helpful.

Thanks @richfab , could you provide some datasets to test eco_labels and required files fixes?

[richfab]

Unfortunately I don't know of any production feed that can test these changes @qcdyx.

Here's a way to test locally:

1. Download each file of a feed (e.g. this Bolt feed that contains the 3 major versions)
2. Introduce errors in the local feed at the places to test
3. Run a server locally in the folder that contains the local feed: python3 -m http.server 8000
4. Run the validator locally and validate the URL of the local feed (e.g. "http://localhost:8000/gbfs.json")

Hey @davidgamez I modified the Bolt feed with empty "feeds" array and got the following result.
