Angular 访问NGRX效果值中的最新存储值未定义

我有两个动作，一个叫做

mergeGuestData

，用于更新状态。在该动作触发后，我想在第一个动作完成时触发另一个动作

onboardGuest

。因此，当

mergeGuestData

调用excute

GuestActions.onboardGuest（）操作时，我使用了
effect

 whenTempCheckComplete$ = createEffect(() => {
    return this.actions$.pipe( 
    ofType(GuestActions.mergeGuestData),
      map((action) => {
          return GuestActions.onboardGuest()
      })
    );
  });

当此
GuestActions.onboardGuest（）
触发时，我需要访问先前修改的
mergeGuestData
操作的状态，并进行服务调用。因此，我创建了另一个效果。这里的问题是
guestData
未定义。如果没有这些数据，我无法提供所有服务。我做错了什么

 onboardGuest$ = createEffect(() => {
    return this.actions$.pipe( 
      ofType(GuestActions.onboardGuest),
      withLatestFrom(this.store.pipe(select(selectGuest))),
      //----- guestData getting undefined-------------
      switchMap(([action, guestData]) => {
        return this.httpClient.post(environment.urls.guestOnboard, guestData).pipe(
          map(({payload}:RequestResult<GuestOnboardSuccessResponse>) => {
               return GuestActions.onboardGuestSuccess({resPayload:payload})
          }),
          catchError((err) => {
            return of(GuestActions.onboardGuestFailure({ error: err }))
          })
        )
      })
    );
  });

减速器

on(GuestActions.mergeGuestData, (state, { gestRelatedData }) => {
    return {
      ...state,
      onBoardGuestInfo: {
        ...state.onBoardGuestInfo,
        onBoardCheckList: gestRelatedData,
      },
    };
  }),
  on(GuestActions.onboardGuest, (state) => {
    return { ...state, isLoading: true };
  }),
  on(GuestActions.onboardGuestSuccess, (state, { resPayload }) => {
    return { ...state, successResponse: resPayload, isLoading: false };
  }),
  on(GuestActions.onboardGuestFailure, (state, { error }) => {
    return { ...state, isLoading: false, error: error };
  })

请包括减速器并显示减速器的初始状态
on(GuestActions.mergeGuestData, (state, { gestRelatedData }) => {
    return {
      ...state,
      onBoardGuestInfo: {
        ...state.onBoardGuestInfo,
        onBoardCheckList: gestRelatedData,
      },
    };
  }),
  on(GuestActions.onboardGuest, (state) => {
    return { ...state, isLoading: true };
  }),
  on(GuestActions.onboardGuestSuccess, (state, { resPayload }) => {
    return { ...state, successResponse: resPayload, isLoading: false };
  }),
  on(GuestActions.onboardGuestFailure, (state, { error }) => {
    return { ...state, isLoading: false, error: error };
  })
