为什么我的模拟电话给了我一个"Cannot read property 'then' of undefined"

我很确定这与异步调用有关，但这是我的大脑所能做到的。

调用功能为：

const { messageNodeResponse } = require('../../../app/lib/message-node-response');
jest.mock('../../../app/lib/am-api.js');
describe('message node response', () => {
it('should check for message node prompt.', async () => {
const req = {
session:
{
payload: {
callbacks: [{
type: 'NameCallback',
output: [{ name: 'prompt', value: 'resendExpiredOTP' }],
input: [{ name: 'IDToken1', value: '' }],
},
{
type: 'NameCallback',
output: [{ name: 'prompt', value: 0 }],
input: [{ name: 'IDToken2', value: '' }],
}],
},
},
};
const res = await messageNodeResponse(req, 'registration');
expect(res.statusCode).toEqual(200);
});
});

正在测试的函数(在消息节点response.js中(：

const messageNodeResponse = (req, api) => {
const requestBody = req.session.payload;
requestBody.callbacks[1].input[0].value = 0;
const apiCall = assignApi(api);
return apiCall(req, requestBody)
.then((result) => {
logger.debug(result.data);
req.session.payload = result.data;
}).catch((err) => {
throw err;
});
};
module.exports = { messageNodeResponse };

运行单元测试会给我以下错误：；TypeError:无法读取未定义的"的属性"then"；参考线"；return apiCall(req，requestBody("；。

根据要求，am-api.js:

const axios = require('axios');
const { v1: uuid } = require('uuid');
const post = async (url, data, req) => axios.post(
url,
data,
{

'Accept-API-Version': 'protocol=1.0,resource=2.1',
language: req.cookies.lng ? req.cookies.lng : 'en',
...(req.session.clientId) && { 'client-id': req.session.clientId },
...(req.session.id) && { 'session-id': req.session.id },
...((req.headers['correlation-id']) && { 'correlation-id': req.headers['correlation-id'] }) || { 'correlation-id': uuid() },
...(req.headers['user-agent']) && { 'User-Agent': req.headers['user-agent'] },
