[AOT] ngc: Error: Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol AppModule

Hi! I recently upgraded to the 2.0.0 release version of Angular 2. I’m getting this error from ngc:

ngc: Error: Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol AppModule

I believe it has to do with this code in the NgModule definition:

StoreModule.provideStore(
        compose(
            localStorageSync(['todos']),
            combineReducers
        )({todos, visibilityFilter})

if I change it to this…

StoreModule.provideStore({todos, visibilityFilter})

it works fine. If I attempt to do what the error says, and replace the function with a reference to an exported function it still does not work:

import { Store, StoreModule } from '@ngrx/store';
import { todos, visibilityFilter } from './reducers';
import { NgModule } from '@angular/core'

export const reducers = compose(
            localStorageSync(['todos']),
            combineReducers
        )({todos, visibilityFilter});

@NgModule({
  imports: [
    BrowserModule,
    StoreModule.provideStore(reducers)
  ]
})
export class MyAppModule {}

Do you have any ideas?

Never mind, here’s how the ngrx example app works around it:

@mxii oh, right. actually my productionReducer and developmentReducer look like this:

const developmentReducer: ActionReducer<State<any>> = compose(
	storeFreeze,
	localStorageSync(['reducerName1', 'reducerName2'], true),
	storeLogger({
		level: 'info',
		collapsed: true,
	}),
	combineReducers)(reducers);

const productionReducer: ActionReducer<State<any>> = compose(
	localStorageSync(['reducerName1', 'reducerName2'], true),
	combineReducers)(reducers);

hope it helps
