rehydrate only works when devtools intrument enabled?

I try to save the authentication information inside localStorage. Now, in development everything worked fine, but in production the information is not rehydrated.

In my root module imports I have the following line:

!environment.production ? StoreDevtoolsModule.instrument() : [],

When I change it to instrument in development as well as in production, suddenly also rehydration of the state works.

StoreDevtoolsModule.instrument(),

Do you have an idea what could cause the problem?

For completeness, here is how I activate ngrxLocalStorage (based on the ngrx example project in app/reducers/index.ts):

export function localStorageSyncReducer(reducer: ActionReducer<any>): ActionReducer<any> {
  return localStorageSync({ keys: ['auth'], rehydrate: true })(reducer);
}

export const metaReducers: ActionReducer<any, any>[] = !environment.production
  ? [localStorageSyncReducer, logger]
  : [localStorageSyncReducer];

I fixed it by moving the meta-reducer into the specific feature module of where i wanted to persist the state

StoreModule.forFeature('auth', reducers, { metaReducers: metaReducers }),

export function localStorageSyncReducer(reducer: ActionReducer<any>): ActionReducer<any> {
    return localStorageSync({ keys: ['status'], rehydrate: true })(reducer);
}

instead of

    StoreModule.forRoot(reducers, { metaReducers: metaReducers }),

export function localStorageSyncReducer(reducer: ActionReducer<any>): ActionReducer<any> {
  return localStorageSync({ keys: [{ 'auth': ['status'] }], rehydrate: true })(reducer);
}

This issue should be resolved as of v5.0.0 thanks to @nhaesler’s PR 👍
