Using AnimationPlayer node can't play character's death animation

[MineGame223]

I'm using AnimationPlayer node in Godot to set animation for my custom character, but the animation "died" just can't play normally. The character just standing there as idle when it should "die". I wonder if it's me loss some methods or just a little bug?
Also, my character doesn't attack The Architect, should I just add an "attack" line in my localization file? or other methods?
If those issues are already fixed or just my wrong coding, please tell me. Thanks!

Have seen the death thing mentioned by someone else as well, will look into it
It might be played normally through a different method than the one that is currently patched

For architect loc - https://alchyr.github.io/BaseLib-Wiki/docs/extras/ancient-dialogue.html#architect-example

If you do not currently have an attack line it would default to only the architect attacking. If it doesn't work after adjusting this, please leave another comment

I've solved the problem about the architect, thank you very much!
