Multiple Validators throwing TypeError

[Coly010]

From short initial investigation it seems like this typing:

reactive-forms/projects/ngneat/reactive-forms/src/lib/types.ts

Line 22 in d57c2d8

validators?: ValidatorFn<T, Partial<E>> | ValidatorFn<T, Partial<E>>[] | null;

Needs to be changed to be recursive in such a way that it can aggregate the different Validators that are used on a FormControl

At the moment, an error is thrown for the following:

email: new FormControl('', [Validators.required, Validators.email])

Which states that {email: true} is not assignable to {required: true}.

I believe this needs a slight change to how the object type is built.

I feel like we might need something similar to this, except with Partial instead of Readonly

After further investigation I've narrowed this down further.

It occurs when we do not pass a Type definition for the formState.

@NetanelBasal I'm coming up blank on how to fix it. My best suggestion right now is to potentially advice users of this scenario.
