Catch connection error is not possible

[vielhuber]

Hello!

From time to time in my script the following error is thrown:

node:events:505
      throw er; // Unhandled 'error' event
      ^

Error: OOPS: priv_sock_get_int
    at makeError (/var/www/test/node_modules/ftp/lib/connection.js:1067:13)

}

Example code:

 var c = new Client();
  c.on('ready', function() {
    c.get('foo.txt', function(err, stream) {
      if (err) throw err;
      stream.once('close', function() { c.end(); });
      stream.pipe(fs.createWriteStream('foo.local-copy.txt'));
    });
  });
  c.connect();

If I wrap c.connect(); with try {} catch {} doesn't change anything.

How am I able to prevent that my script gets stuck any properly catch those errors?

Simple solution:

  c.on('error', function(err) {
      console.log(err);
  });
