🐞[BUG]: Using InjectionToken breaks Dependency Injection in state classes

[Mathyn]

Affected Package

@ngxs/store

Is this a regression?

Unsure

Description

When injecting a token in a state class an "Invalid provider" error is thrown when using an InjectionToken. Things work fine however when using a string.

e.g.

This does work:

constructor(@Inject('SOME_TOKEN') someToken: string) {}

This does NOT work:

constructor(@Inject(SOME_TOKEN) someToken: string) {}

🔬 Minimal Reproduction

You can find a Stackblitz example demonstrating the problem here.

To reproduce the error go to src/app.config.ts and change the CUSTOMER_CONFIG definition to the InjectionToken variant (just remove the single quotes). Next go to src/zoo.state.ts and change the constructor dependency injection to again use the InjectionToken variant (again remove the single quotes).

On top of that please find the original Stackoverflow question about this here.

It's an invalid provider because there's a circular dependency between your modules: app.config imports ZooState, and ZooState imports app.config.
