sending "resume spotify" ends in 500

[ma-karai]

To reproduce:
call http://hassio.local:5000/command?message="turn on all lights works"
call http://hassio.local:5000/broadcast_message?message="resume spotify" does not it ends in a 500 error.

Any Idea why this is the case?

Error sending message. Response 500: INTERNAL SERVER ERROR:
7:56 AM /usr/local/lib/python3.6/site-packages/homeassistant/components/notify/rest.py (ERROR)

As far as I know, media commands (such as Spotify) does not work with this add on. I tried to get this to work many times but it doesnt work.
