Another issue with TTS google

Hi, I am trying to realize a welcome home message when I come back at home. The automation works well (in fact the lights turn on) but there is no welcome message from my google home. The strange thing is that if I use the following code in service call panel it works:

"entity_id": media_player.salotto,
"message": "Test, one, two ,three."

But the following action is not working:

service: tts.google_say
      entity_id: media_player.salotto
      messagge: >
           Welcome back!

The error from log is:

Error doing job: Task exception was never retrieved

Traceback (most recent call last):

I’m having the same problem as well. Has anyone yet managed to find a solution to fix this?
