GeckoLib Animated Entity throws error on run attempt.

https://pastebin.com/m1tXY83P

As per what the title says, after adding an Animated Entity with GeckoLib, it throws the above linked error instead of running. As far as I am aware, I followed the tutorial to the letter, and I am not entirely sure what the log is trying to tell me (something to do with @Override and the renderer, neither of which I know how to rectify) or how to fix it. If it helps, the mob is called Buried.
