python - What is causing this JSONDecodeError?

问题描述

I am trying to setup the itunes Media Player in HASSio. I have the REST API running on my mac, and I am able to pull it up in my browser and see that it is running. From within HA, I am able to adjust the volume and change to the next song, however it will not tell me what is currently playing. the below code is what is output to the log whenever I try and do anything adjust volume, start/stop, forward/reverse.

HASS - 0.84.6

ITUNES - 12.2.1.16
