Error occurred while trying to proxy request

使用 proxy报错
Error occurred while trying to proxy request
node 版本 10+
代码

const proxy = require('http-proxy-middleware');

module.exports = function(app) {
  app.use(
    proxy('/api', {
      target: 'http://xxx.xxx.xx.xxx:8080',
      pathRewrite: { '^/api': '' },
      secure:false
    })
  );
};

排查了好久
解决办法
添加请求头设置Connection：keep-alive

module.exports = function(app) {
    app.use(proxy('/api', {
        target: 'http://127.0.0.1:8080/',
        pathRewrite: { '^/api': '' },
        secure:false
        headers: {
            "Connection": "keep-alive"
        },
    }));
};
