Can't add reducer to app.module

[Gadziu1]

I keep all reducers in one const

export const reducers: ActionReducerMap<AppState, any> = {
  router: routerReducer,
  projects: Projects.projectsReducer,
  signalr: signalrReducer
};

In app.module I have

imports: [
    StoreModule.forRoot<AppState, any>(reducers, {
      metaReducers,
      runtimeChecks: {
        strictStateImmutability: true,
        strictActionImmutability: true
      },
    }),

And I got error

Type '{ router: (state: RouterReducerState | undefined, action: Action) => RouterReducerState; projects: (state: State | undefined, action: Action) => State; ... 6 more ...; signalr: (state: BaseSignalRStoreState | undefined, action: Action) => BaseSign...' is not assignable to type 'ActionReducerMap<AppState, any>'. Object literal may only specify known properties, and 'signalr' does not exist in type 'ActionReducerMap<AppState, any>'.ts(232

I found solutions it was missing in my app.reducers files

export interface AppState {
  signalr: BaseSignalRStoreState;
}
