Error 500 calling /api/services/tts/google_say

POST http://HOSTNAME:8123/api/services/tts/google_say
Header: {“x-ha-access”: “mypwd” }
Body: {“message”: “Hello” }

Returns 500 Internal Server Error / Server got itself in trouble

Am I missing something? Thx!

update! this works :slight_smile:

{“message”: “Hello”, “entity_id”: “speaker name” }
