Hi,
sorry if this is not the right place for this error bellow.
Ruby 2.5.5
Rails 2.5.3
json_schema-0.20.6

I got next error.
When I try to match occupancy.json, everything works fine.
When I try to match occupancies.json I got this error.

Schema files are bellow. Can't figure why it's happening!!

Error:

I think I've run into something similar, and I didn't have the time to debug it properly at the time, so I made a workaround that used a fake URL for the $id. Something like this:

"$id": "https://schemas.yourdomain.com/occupancy.json",

And then reference it in items:

"items": { "$ref": "https://schemas.yourdomain.com/occupancy.json#/definitions/occupancy" }

Let me know if that works—if it doesn't I'll try to make a failing test so we can debug.
