Unable to connect to OctoPrint by specifying port in JS library

General
1

A BAD REQUEST error occurs when trying to connect to OctoPrint with the code below. Looking at the caught error, it was responseJSON: {error: 'port is invalid'}.
http://192.168.0.17:5000/ from a web browser displays the GUI normally. Can you guess what's wrong?

Client = new OctoPrintClient({
baseurl: 'http://192.168.0.17:5000/',
apikey: serverApikey,
});
Client.files.list();

From what kind of environment are you trying to run this code?

I am not sure where in OctoPrint I would find an error message for the port being wrong, I am surprised to see that.

Dear Charlie Powell

Thank you for your reply.
sorry. It was due to my careless mistake.

After much research, the Promise on OctoPrintClient.connection.connect failed and the responseJSON was {Error: 'Invalid port'}. I just didn't connect the 3D printer to the serial port.
I'm embarrassed, I'm sorry.
