/ Sockjs-node / info error problem

1.vue.config.js

The reason is related to the proxy server does not support ws, ws therefore need to be closed at the broker, that is ws: false

const ds_proxy = {
  '/': {
    ws: false,
    target: 'https://dev.test.gitinn.com/',
    changeOrigin: true,
  },
}

  } the catch (E) { 
    self.emit ( ' Finish ' , 0 , '' ); 
    self._cleanup ( to false );
