Failed to call service spotcast/start (400 Client Error)

See original GitHub issue

Hi,

I’m unable to call the spotcast.start service on Home Assistant 0.99.3 docker image and spotcast 2.2 (installed via HACS 0.14.2) due to the following error Failed to call service spotcast/start. 400 Client Error: Bad Request for url: https://accounts.spotify.com/api/login

The service parameters I tried:

{
  "entity_id": "media_player.chromecast",
  "uri": "spotify:playlist:37i9dQZF1DWXRqgorJj26U"
}

Previously I had no issue setting up the Spotify media player component (https://www.home-assistant.io/components/spotify/) and can control the playback on my chromecast source. Googling around show this past issue that has been resolved https://github.com/balloob/pychromecast/issues/264.

Please find the following error log upon the spotcast.start service:
