More specific error messages when a problem is encountered with the configuration [vol2]

**Is your feature request related to a problem? Please describe.**

This has already been solved by https://github.com/dotansimha/graphql-code-generator/issues/6355 but it kind of seems like the problem is still there.

**Describe the solution you'd like**

I'm running codegen and getting

```
✖ Invalid Codegen Configuration!
◼ Generate outputs
```

I don't know whats wrong. I'd like a stacktrace or some more concrete message.

**Describe alternatives you've considered**

`VERBOSE=1 DEBUG=1`
