错误：动作必须是普通对象。使用自定义中间件执行异步操作。在React Native中

每当我尝试分派动作时，都会收到此错误消息：

错误：动作必须是普通对象。使用自定义中间件执行异步操作。

我已经安装了redux-thunk并且没有异步操作，它正在运行。

存储配置：

import { applyMiddleware, createStore } from 'redux';
import thunk from 'redux-thunk';
import { createLogger } from 'redux-logger';
import { composeWithDevTools } from 'redux-devtools-extension';

import reducers from '../reducers/index';

const logger = createLogger();

export default createStore(reducers, composeWithDevTools(applyMiddleware(thunk)));

使用者介面：

...
import { connect } from 'react-redux';
import { getCities } from '../../actions/cities';
...
componentDidMount = async () => {
    try {
      const cities = await this.props.getCities();
      console.log(cities);
    } catch (error) {
      console.log(`errorhome: ${error}`);
    }
    SplashScreen.hide();
  }
...

const mapDispatchToProps = dispatch => ({
  changeNetworkStatus: () => dispatch(changeNetworkStatus),
  getCities: () => dispatch(getCities),
});

export default connect(mapStateToProps, mapDispatchToProps)(Home);

行动：

import database from '../config/utils';

export const GET_CITIES_START = 'GET_CITIES_START';
export const GET_CITIES_FINISHED = 'GET_CITIES_FINISHED';
export const GET_CITIES_ERROR = 'GET_CITIES_ERROR';

const getCititesStart = () => ({ type: GET_CITIES_START });
const getCititesFinished = cities => ({ type: GET_CITIES_FINISHED, cities });
const getCititesError = error => ({ type: GET_CITIES_ERROR, error });

export const getCitites = () => async (dispatch) => {
  dispatch(getCititesStart());
  try {
    const cities = [];
    const snap = await database.ref('cities').once('value');
    console.log('snap: ', snap);
    snap.forEach((element) => {
      const city = {
        city: element.key,
        coordinate: element.val().coordinate,
      };
      cities.push(city);
    });
    dispatch(getCititesFinished(cities));
  } catch (error) {
    dispatch(getCititesError(error));
  }
};

编辑：如果我也添加logger到中间件，错误消息是这样的：

TypeError：无法读取未定义的属性“类型”

谢谢你的帮助！
