Modding Help (Beginner)

Hello, I am fan of the original books and somewhat of the Netflix adaptation so I've decided to play through Witcher 3 with some mods. (I am very new at this) I can't run the game and I keep getting these errors.

Here is a list of my Script Compilations Errors:

Error [modextraskillslotsnextgen]local\essconfig.ws(112): 'essconfig' is not a member of 'handle:CR4Game'

Warning [content0]engine\environment.ws(30): Global native function 'EnableDebugOverlayFilter' was not exported from C++ code.

Warning [content0]engine\environment.ws(32): Global native function 'EnableDebugPostProcess' was not exported from C++ code.

Warning [content0]engine\showflags.ws(11): Global native function 'DebugSetEShowFlag' was not exported from C++ code.

Please let me know what I should do. Thank you in advance :)
