你好 ，老师，我按照您的课程《微服务摸鱼君》在编写代码时 ，出现问题，在学习第31节集成验证码到模块中时，我已将验证码的后台代码集成到我的后台应用，也将前端代码集成到我的前端页面，并修改了 axios.defaults.baseURL，但是前台页面仍然不能显示验证码模块，前端页面显示




      <strong>We're sorry but vicon-usercenter doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>

控制台报错信息如下：

Uncaught TypeError: Cannot read properties of undefined (reading 'defaults')
    at eval (axios.js?f837:3:1)
    at ./src/components/verifition/utils/axios.js (app.js:319:1)
