I'm getting an error when trying to fix LScustoms in VRP

Hey, I’m using VRP as my framework. So I’m trying tu use Sighmir fix (tried a lot of others).
I do everything as they said, but I get this error when someone try to buy a car custom.

And after that, the player can’t access the garage. I searched everywhere before posting, no luck.
