'dict object' has no attribute - Panasonic Blu-ray Intergration

Hi new to home assistant i have installed the Panasonic Blu-ray integration however it’s not working correctly. It can turn on and off the player but it does not detect it’s state or allow any other control.

My log is below, this is a new install as well any help would be appreciated as I can’t find any information to assist me?
