Need Dependancy Help

I am making a Minecraft horror entity mod and I'm working on a custom AI. I'm fairly new to modding so I'm using someone Elses custom AI and ill be customizing it to make it my own. the problem is that before I went to customize it, I decide to test out the pre build AI to make sure it works and I'm glad I did. when I tried to add the Ai to the, "On Entity Initial Spawn" trigger it was saying missing dependancys. I think I understand the issue but it seems like there is no general fix and its mostly just based on the code you wrote. so what do I need to do to fix this? It has 0 warnings or errors.

Im posting 2 different screenshots.

The Code.

And the Required dependency's that its showing. Pls help.
