NestJS config validate function

Question

I use in the NestJS config module a custom validate function.

When I run my app in the development mode there are any problems, bu in the production mode if my validate function throws an exception I see a listing of my code after webpack and just after it is shown an error text. How to avoid of printig a code listing?
