reactjs – “动作必须是普通的对象.使用自定义中间件进行异步操

在我的react / redux应用程序中,当我在我的一个操作中发出ajax请求时,它会抛出此错误：
未捕获的错误：操作必须是普通对象.使用自定义中间件进行异步操作.

我的商店创建如下：

import { composeWithDevTools } from 'redux-devtools-extension';
import reducers from './reducers';
import thunkMiddleware from 'redux-thunk';
import { applyMiddleware,createStore } from 'redux';

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

相关的减速器看起来像这样：

import * as actions from './../../actions/tools/vehicle-lookup';

const defaultState = {
	vrm: void 0,isLoading: false,response: void 0,error: void 0,};

export default function (state = defaultState,action) {
	switch (action.type) {
		case actions.VEHICLE_LOOKUP:
			return { ...state,isLoading: true,vrm: action.vrm };

		case actions.VEHICLE_LOOKUP_SUCCESS:
			return { ...state,payload: action.payload,error: void 0 };

		case actions.VEHICLE_LOOKUP_FAILURE:
			return { ...state,error: action.error,response: void 0 };

		default: return state;
	}
}

相关行动如下：

import axios from 'axios';

export const VEHICLE_LOOKUP = 'VEHICLE_LOOKUP';
export const VEHICLE_LOOKUP_SUCCESS = 'VEHICLE_LOOKUP_SUCCESS';
export const VEHICLE_LOOKUP_FAILURE = 'VEHICLE_LOOKUP_FAILURE';

export function fetchVehicleLookup(vrm: string,jwt: string) {
	return function (dispatch) {
		dispatch(requestVehicleLookup());

		axios.create({
			timeout: 4000,})
			.post('/*api url*',{
				action: '*method*',body: { vrm },})
			.then(response => response.data)
			.then(json => dispatch(receiveVehicleData(json)))
			.catch(error => dispatch(receiveVehicleDataFailure(error)));
	};
}

function requestVehicleLookup() {
	return { type: VEHICLE_LOOKUP };
}

function receiveVehicleData(payload: object) {
	return { type: VEHICLE_LOOKUP_SUCCESS,payload };
}

function receiveVehicleDataFailure(error: object) {
	return { type: VEHICLE_LOOKUP_FAILURE,error };
}
