ValueError("A relative URL was received on '{entity}.{attribute}'.

[Dean98T]

In the logs for the AppDaemon app whenever I run this, as soon as the Spotify entity picture changes, with it being a relative URL, I get the following error message:

  File `/config/apps/media_lights_sync.py`, line 174, in format_url
    raise ValueError("A relative URL was received on '{entity}.{attribute}'.\nha_url must be specified in the configuration for relative URLs.".format(
ValueError: A relative URL was received on 'media_player.spotify_dean_taylor.entity_picture'.
ha_url must be specified in the configuration for relative URLs.

You are receiving this error because your ha_url does not seems to be recognized by the script. This error will only be thrown if if not is_absolute and self.ha_url is None (ref)

Could you try restarting your AppDaemon?

Or maybe try switching it up for your server IP address: ha_url: http://192.168.0.199:8123/
