I have a common functionality to get items from server.

export const getAllEffect = <TEntity, TData>(args: InputArgs<TEntity, TData>) => {
  const {
    actions$,
    entity,
    subExists$,
    getAllApi,
    collectionIdFn,
  } = getParams(args)

  const getAllTrigger$ = actions$.pipe(
    ofActionAndPayload<GetAllPayload<TData>>(AsyncActions.GetAll),
    ofEntity(entity));

  // Force triggers ignore subscriptions for collection
  const forceTriggers$ = getAllTrigger$.pipe(filter(({ force }) => force))
  const softTriggers$ = getAllTrigger$.pipe(filter(({ force }) => force))
  const softTriggersFilteredBySub$ = softTriggers$.pipe(filterSubExistsWithCancellation(subExists$))

  // Emits load action when all filters are passed otherwise returns undefined (to cancel request)
  const trigger$ = merge(forceTriggers$, softTriggersFilteredBySub$)
  const cancelAction$ = of(new LoadActions.SetLoading(entity, false))
  const preLoadAction$ = of(new LoadActions.SetLoading(entity, true))
  const getPostLoadActions = (trigger: GetAllPayload<TData>) => (entities: TEntity[]): Action[] => {

    return [
      new CollectionActions.AddAll(collectionIdFn(trigger.data), entities),
      new LoadActions.SetLoaded(entity, true),
      new LoadActions.SetLoading(entity, false),
    ]
  }

  const getFailedActions = (trigger: GetAllPayload<TData>) => (response: HttpErrorResponse): Action[] => {
    return [
      new AsyncActions.GetAllFailed({ entity, response, data: trigger.data, count: trigger.count }),
      new LoadActions.SetLoading(entity, false),
    ]
  }
  
  return trigger$.pipe(
    switchMap((trigger) => {
      debugger;
      // Don't do any loading + cancel prev request if present
      if (!trigger) return cancelAction$
      return concat(
        preLoadAction$,
        getAllApi(trigger.data).pipe(
          retry(apiRetryCount),
          switchMap(getPostLoadActions(trigger)),
          catchError(getFailedActions(trigger)),
        ),
      )
    }),
  )
}

The trigger merges all effects to be executed.
The effect is ran, I can debug it.
but I never get to the switchMap part where debugger is written. I don’t know why.
