Unhandled 'error' event with Connection.js

Im still trying to figure out why an error emitted by connection could be "unhandled" because the only place where Connection were created is at client.js:

 Client.prototype.connection = function() {
    var conn, connectListener, errorListener, resolver;
    resolver = Promise.defer();
    conn = new Connection(this.options).on('error', errorListener = function(err) {
      return resolver.reject(err);
    }).on('connect', connectListener = function() {
      return resolver.resolve(conn);
    }).connect();
    return resolver.promise["finally"](function() {
      conn.removeListener('error', errorListener);
      return conn.removeListener('connect', connectListener);
    });
  };

and there is an .on('error') . so what Im missing here? pease help.

hey guys, I managed to solve this issue. the reason for the error Unhandled error at: Error: write EPIPE occurs is because the Connection object is shared and its error listener was removed once client done with connecting. but error event could still be emitted after connection is established. you can reproduce this bug like this:

1. create a sync service;

2. start pushing some file using sync.pushFile

3. cutting off device network before the pushing complete.

then you probably get an unhandled error. the way I solve this is add _this.connection.on('error', ...) inside sync
