How do I authorize to work with Google forms?

When I want to get authorization data I get this error:

Error: listen EADDRINUSE: address already in use :::3200

This port is not busy. The error occurs only when it starts executing this request.

The request is executed at the address: http://localhost:3200/api/run

What am I doing wrong?

const path = require('path');
const { authenticate } = require('@google-cloud/local-auth');


module.exports.runSample = async function () {
    const auth = await authenticate({
        keyfilePath: path.join(__dirname, 'credentials.json'),
        scopes: 'https://www.googleapis.com/auth/forms.responses.readonly',
    });
    console.log(auth)
}

credentials.json:

{
    "web": {
...
        "redirect_uris": [
            "http://localhost:3200/oauth2callback/"
        ]
    }
}
