Error during setup of component webostv in 0.104.3

Hardware

Hi
I am having problems setting up my LG TV.
I am running HA on version 0.104.3 on docker.
I have this in my Configuration;

webostv:
  host: 192.168.1.5
  name: Living-Room-TV
  standby_connection: true
  turn_on_action:
    service: persistent_notification.create
    data:
      message: "Turn on action"
  customize:
    sources:
      - livetv
      - youtube

I can ping the TV from HA.
I have previously had this working on previous versons of HA.

now I get the error;

Traceback (most recent call last):

    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 2 column 1 (char 1)

What am I missing?

With this configuration variable set to true, did you also enable Standby+ on your TV, as stated in the documentation? On my C8, this setting is found in the General category of the settings, and it’s called Quick Start+.

This will not be the cause of your issues, but this bit makes no sense to me (note: I see it in the docs too). turn_on_action should define how your TV can be turned on. I don’t see how creating a persistent notification will accomplish that. Further down in the docs, this setting is explained correctly.
