Why is Event end throwing an error?

Question

Node.js

Here is the script and the error

var myserver = require('http').createServer().listen(8080);
myserver.on('request', function(x, y){
  y.write("1");
  x.on('data', function(z){
    console.log(z.toString());
    //process.stdout.write(msg.toString());
  });
  x.on('end', function(){
    y.end();
  });
});

Answer 1

Duck, after all, immediately after the end of the x.on('end') request, you also complete the response y.end()
