Caused by: java.lang.IllegalArgumentException: Unable to find model file:

[Ineedhelppleasehelpmeibeg]

I want to add a geckolib(5.0.0) entity model and animations into the latest version of forge, minecraft 1.21.5
but I've tried everything and it seem like it didnt work, I have finished the Render, Model, Register, Entity creation script and all that, and I 100% have geckolib downloaded(in libs folder)
 

The file path should be correct too (idk i may be stupid)

but everytime i run minecraft i just end up having a issue :
Caused by: java.lang.IllegalArgumentException: Unable to find model file: modded_boss_fight:geo/toaa

and instantly crashing, even though using a print statement shows that its looking down the right path
and also i tried deleting and readding those files just incase it was corrupted, but I dont know

Im new and I couldnt find much to help me online so I come to hopefully idk someone save me

It's complaining about a missing model file. Can you post a screenshot with the contents of the assets/modded_boss_fight/models folder?
