the port debug is not working

Ciao!
How are you?

Component	Version
Operating system	Linux server 4.12.0-1-amd64 #1 SMP Debian 4.12.6-1 (2017-08-12) x86_64 GNU/Linux
Node.js	v8.5.0
Chrome/Chromium/...	/opt/google/chrome/chrome --remote-debugging-port=32231 --headless --disable-gpu --enable-logging --log-level=0 --user-data-dir=/var/p3x/server.patrikx3.com/cache/chrome --user-agent="corifeus-server-renderer" about:blank

| chrome-remote-interface | latest in npm

Is Chrome running in a container? YES / NO

I execute Chrome, like this:
/opt/google/chrome/chrome --remote-debugging-port=32231 --headless --disable-gpu --enable-logging --log-level=0 --user-data-dir=/var/p3x/server.patrikx3.com/cache/chrome --user-agent="corifeus-server-renderer" about:blank

But I get this error:

 { Error: connect ECONNREFUSED 127.0.0.1:9222
    at Object._errnoException (util.js:1026:11)
    at _exceptionWithHostPort (util.js:1049:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1174:14)
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect',
  address: '127.0.0.1',
  port: 9222 }

I did not change anything, but now suddenly (I automatic update with npm-check-updates so it is possible I updated this npm). I get this error. Why is it trying to looking for 9222 when I specified the port and I can telnet in with the port as well.

Do you have an idea why it is happening?

But I get this error:

Doing what?

Show me the command or the code that you're using.

[p3x-robot]

            const client = await CDP({
//                port: port,
                target: `ws://localhost:${port}/devtools/browser`
            });

The port is the port I am using, why do is it .
Ok, I added in the port , removed the // port : port, now it works.

Sorry, so now the port in CDP is required, before it was working.
Weird.
Ciao! Thanks!

[p3x-robot]

So now I have to use the target or the port? What is the different? I just have no idea, you know what is happening with the target and the port on the CDP options?

[cyrus-and]

The port is not required, it just defaults to 9222.

I just have no idea

Does this give you a clue?

[p3x-robot]

yeah, i use both since they are the same otherwise its not working, thanks.
