Redux Dev Tools不显示状态更改，action.payload为{}

Question

我试图弄清楚为什么Redux-Devtools不显示状态变化，因为它显示action={ type: 'GET_LOCATION_SUCCESS', payload: {} }，而debugger和console.log()显示action.payload为n。 我正在使用

• redux-observable
• rxjs
• typesafe-actions

这是我的动作创建者：

import { createAsyncAction } from 'typesafe-actions';
import { GET_LOCATION_BEGIN, GET_LOCATION_FAILURE, GET_LOCATION_SUCCESS } from './constants';

export const getMyLocation = createAsyncAction(
    GET_LOCATION_BEGIN,
    GET_LOCATION_SUCCESS,
    GET_LOCATION_FAILURE
)<undefined, Position, string>();

这是我的减速器

import { RootAction } from 'MyTypes';
import { combineReducers } from 'redux';
import { getType } from 'typesafe-actions';

import {getMyLocation} from '../actions/locationActions';

export type locationState = {
    position: Position;
    error: boolean;
};

export const locationReducer = combineReducers<locationState, RootAction>({
    position: (state = {} as Position, action) => {
        switch(action.type){
            case getType(getMyLocation.success):
                return action.payload;
            default:
                return state;
        }
    },
    error: (state = false, action) => {
        switch(action.type){
            case getType(getMyLocation.failure):
                return true;
            default:
                return state;
        }
    }
})

这是我的史诗：[编辑v.1]

   export const getMyLocationEpic: Epic<RootAction, RootAction, RootState, Services> = (action$, state$, {geoLocation}) => 
  action$.pipe(
    filter(isActionOf(getMyLocation.request)),
    switchMap( () => geoLocation.getGeoLocation(options).pipe(
        take(1),
        mergeMap( (data : Position) => of(
          // Dispatch action with my location data and then dispatch action to request weather from API. It runs fetchWeatherEpic
          getMyLocation.success(data),
          fetchWeather.request(data)
          )
        ),
        catchError(err => of(getMyLocation.failure(err)))
      )
    )
  );

我想知道不显示状态更新的原因可能是什么，它在console.log()中应有的作用，但在devtools中不起作用。
