Current behavior

I setuped configuration validation as described in documentation of NestJS: https://docs.nestjs.com/techniques/configuration#schema-validation

Validation works as expected, but when my .env file is not valid, I am getting plain error, for example:

Error: Config validation error: "FOO_BAR" is required at Function.forRoot (@nestjs\config\dist\config.module.js:44:27)

This error is not thrown by Nest so approach with globalFilter what can catch every Nest error not work: https://docs.nestjs.com/websockets/exception-filters#exception-filters

Can this be described in documentation?

What's the use-case here?

[Baterka]

Having errors catchable to be able to reformat them, or at least having them in NestJS exception format (for example like @nestjs/typeorm errors).
Or maybe just use Nest's logger to throw errors? I am working on it in fork :)
