Casting Youtube to Chromecast not working

Background - attempting to cast a Youtube video to a cromecast device. I can cast local media and media stored in Google Drive so I know the chromecast is working. And I’ve confirmed that the media extractor has been added to the configuration.yaml file. And I know the url is ligit as I’ve pasted it in firefox and the video come right up.

Here is the script YAML

alias: New Script
sequence:
- service: media_extractor.play_media
entity_id: media_player.chromecast0324
data:
media_content_id: "https://youtu.be/kAoLNs2xshU"
media_content_type: video/youtube

Can someone tell me what I am doing wrong here?
