JSON Pathing issue

Got a new REST sensor looking at a local file (updated via a python script):

- platform: rest
  scan_interval: 60
  resource: http://<MY_IP>:8123/config/www/json_file.txt
  name: "newtest"
  value_template: "Ok"
  json_attributes_path: "$"
    - destination
    - min_to_bus

JSON file looks like this:

        "destination": "Bellevue GE, Valavran",
        "min_to_bus": 0
    }, {
        "destination": "Gex, L'Aiglette",
        "min_to_bus": 3
    }, {
        "destination": "Genève, Cornavin",
        "min_to_bus": 5
    }, {
        "destination": "Ferney, mairie",
        "min_to_bus": 10

I’ve played with all the normal JSON parsing tools but can’t for the life of me get the sensor to read the attribute data. The sensor merely comes back with a value of “Ok” and no attribute info. Am I missing something obvious?

Thanks as usual! Stimulating and fun (and frustrating!)
