Playing audio clips as RASA response

Hello @rctatman,

Thank You for your response. i Have already seen that and implemented it. For AI voice clips i have thousands of recording to play the voice note. My issue is mentioned here .

On my windows system i used this to make utterance worked for autoplay :

  utter_recording:
  - custom:
    attachment:
      type: video
      payload:
        src: fullpath/filename.mp4
      autoplay: true

It worked perfectly fine. But when i tried doing the same on GCP like this :

  utter_recording:
  - custom:
    attachment:
      type: video
      payload:
        src: /etc/rasa/files/video.mp4
      autoplay: true

I get this error in webchat widget :

Any luck finding solution either autoplay videos via link or local files on GCP will be very helpful.
