action payload in the effect

Question

I have the following code

  @Effect()
  executeMission$ = this.actions$.pipe(
    ofType<featureActions.ExecuteUsedDroneMissionRequest>(featureActions.ActionTypes.ExecuteUsedDroneMissionRequest),
    withLatestFrom(this.store$.pipe(select(MissionsStoreSelectors.selectAllEntities))),
    switchMap(([action, missions]) => {
      const mission = missions[action.payload.missionId] 
      //....
    })
  );

Now, I have a selector which is supposed to remove this line => const mission = missions[action.payload.missionId]

export const selectAllEntities: (state: object) => Dictionary<IMission> = featureAdapter.getSelectors(selectMissionState).selectEntities;
export const getById = () => createSelector(
  selectAllEntities,
  (entities, props) => entities[props.routeId]
);

but to use it, I need to add the action payload into the withLatestFrom like this

withLatestFrom(this.store$.pipe(select(MissionsStoreSelectors.selectById(), { missionId: action.payload.missionId }))),

but action is not available outside the switchMap.

Is it possible to do this ?

Answer 1

Use a concatMap, this example comes from my post Start using ngrx/effects for this

 concatMap(action =>  
    of(action).pipe(
      withLatestFrom(store.pipe(select(getUserName)))
    )
  ),
