After adding video_controller.js and updating the content_tags the video is no longer showing, and I'm getting this warning in the console.:

guide.js:19 Please replace data-target="video.player" with data-video-target="player". The data-target attribute is deprecated and will be removed in a future version of Stimulus. video 

 I'm not sure if the warning is why it's not showing, but I also can't figure out how to format the content_tag to change that attribute. Any advice? Cheers.
