我通过axios Error: Request failed with status code 400连接到API时遇到问题
有人能帮帮我吗
我的服务/API。js：`

const axios = require("axios");

const api = axios.create({
  baseURL: "https://url.com"
});

api.interceptors.request.use(async config => {
    config.headers.access_token = `token123`;  
    return config;
});

module.exports = api;

我的控制器：

const api = require('services/api');
    router.post('/', async (req, res) => {    
       try {
         const response = await api.post("/api", JSON.stringify(data));
         return response;
        } catch (err) {          
          return res.status(400).send({ erro: err })
        }
    })

    module.exports = app => app.use('/routes', router)

但是当我发出请求时，我得到了错误
