Integration doesn't seem to be working anymore

[Sjorsa1]

I get the following errors when starting up homeassistant with this integration:

2020-07-12 16:12:52 ERROR (MainThread) [homeassistant.components.device_tracker] Error setting up platform legacy
Traceback (most recent call last):

File "/config/custom_components/phonetrack/device_tracker.py", line 61, in _update_info
data = data[self.token]
TypeError: list indices must be integers or slices, not str```

Is there anything I can do to fix this?

@Sjorsa1 and maybe others that see this issue. This error occurs when your token is wrong as the phonetrack API returns an empty list [] when the token does not exist.
You can test this yourself by navigating to the url https://<nextcloud-domain>/index.php/apps/phonetrack/api/getlastpositions/<your token> and it should return a json object like (I replaced all values of mine with 0):

{
  "<token>": {
    "<device_name>": {
      "useragent": "PhoneTrack/0.0",
      "lat": 0.0,
      "lon": 0.0,
      "timestamp": 0,
      "batterylevel": 0,
      "satellites": 0,
      "accuracy": 0,
      "altitude": 0,
      "speed": 0.0,
      "bearing": 0.0
    }
  }
}
