extra keys not allowed @ data['media_player_entity_id'] on channel with Google speakers

[aL3x80]

0.8.3

What version of Home Assistant are you using?

2026.7.4

The problem

When the notification triggers, the other two channels (push and Telegram) work without issues, but for the voice notification, I consistently get error.

What is your channels configuration for Universal Notifier?

I set up a voice notification channel on my Google devices using tts.google_translate_say as the service and media_player.cucina (my speaker) as the entity_id. I enabled TTS and saved the configuration.

What actions did you take in the developer tools?

I tested the tts.google_translate_say service on the speaker, and it works properly.

Anything in the logs? Paste it here!
