Media_player does not support action media_player.play_media

As per title, I keep getting this error on my custom component. I am stuck in getting this to work properly. What could cause this error?

I noticed some time ago that there was an undocumented action media_player.media_play. I never really looked into it, perhaps you need to use that action instead.

Hi I noticed that too. Thanks! I found the error, it was just me.
