Tts does not work according to the documentation

Hi

why does tts not work according to documentation in Czech when cz is available

Why doesn’t it surprise me that everyone is silent. Nobody will be helped here

configuration.yaml only:

tts:
  - platform: google_translate

and script or action:

  - service: tts.google_translate_say
    entity_id: media_player.tablet_jiri
    data:
      message: tady se pomoci nedočkáte
      language: cs

vytvořte si “script” a v file manageru pod jeho číslo vložte:

  alias: 000000009 - řeč na text
  sequence:
  - service: tts.google_translate_say
    entity_id: media_player.vas_konkretni_prehravac
    data_template:
      message: Teplota v obýváku je právě {{states('vas_skutecny_senzor')}} °C.
      language: cs
  - wait_template: ''
    timeout: 00:03:00
    continue_on_timeout: true
  - service: tts.clear_cache
    data: {}
  mode: single

What changed again in 0.115.4 The template worked in the previous version and is now broken

what this error says Error executing script. Unexpected error for call_service at pos 1: Invalid MultiSpec data: TextFrame(encoding=<Encoding.UTF8: 3>, text=['cs'])
