axios post请求挂起在有效请求上

const Router = require('express').Router;
const router = Router();
const axios = require('axios').create({
    baseURL: 'https://some-service.com'
});

const auth-handler = require('auth-handler');

router.post('/', (req, res) => {
    auth-handler.getToken('token-name')
        .then(token => {
            const body = {
                subject: "subject",
                body: "body"
            };

            const options = {
                headers: {
                    'Authorization': 'Bearer ' + token,
                    'Content-Type': 'application/json'
                }
            };
            return axios.post('/'+req.body.route+'/endpoint?foo=bar', body, options);
        })
        .then(response => res.status(response.status).send(response.data))
        .catch(error => {
            console.error(error);
            res.status(error.status).send(error.data);
        });
});
