No provider for InjectionToken Global Config! error

After updating from angular 11 to 13 all my child routes became broken and i am getting this error

ERROR NullInjectorError: R3InjectorError(ArchViewModule)[InjectionToken Global Config -> InjectionToken Global Config -> InjectionToken Global Config -> InjectionToken Global Config -> InjectionToken Global Config -> InjectionToken Global Config]:

What is Global Config InjectionToken? Did't find any info about it or how it is provided to any angular app

Solution

I just had the same problem (after updating Angular from 11 to 13).

In my case the error was:

ERROR NullInjectorError: R3InjectorError(n)[InjectionToken Global Config -> InjectionToken Global Config -> InjectionToken Global Config]:

I've found out that the problem was related to a library I am using in my Angular project (which is Anguar Material Design Progress Buttons).

This library has to be imported as follows (inside the AppModule):

import { MatProgressButtonsModule } from 'mat-progress-buttons';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [MatProgressButtonsModule.forRoot(), ...],  
  bootstrap: [AppComponent]
})
export class AppModule {
}

but i was missing the forRoot() call for MatProgressButtonsModule (which was not necessary before updating Angular: it wasn't present and the App always worked perfectly fine).

Probably your problem is of the same nature: check that all the libraries you're using are imported in a correct way inside the AppModule, calling forRoot() when required.
