Got Not authorized when use dir function

I'm trying to use the function dir:

const Netstorage = require('netstorageapi')

// Defaults: SSL: false
// By default no proxy is set
const config = {
hostname: "hostname",
keyName: "keyName",
key: "key",
cpCode: "cpCOde",
ssl: false,
}
// Don't expose KEY on your public repository.

const ns = new Netstorage(config)

ns.list('test', (err, response, body) => {
      if (err) {
        console.log('err: ', err)
      }
      console.log('body: ', body)
    })

Whatever the path I put (valid or not) I get the same message:

body:  { message: 'Not Authorized.' }

What's wrong?

Start at the ns.list entry point shown in the report and trace how the hostname, keyName, key, and cpCode configuration is used for authorization. Compare those inputs with the NetStorage API requirements; done means identifying why valid and invalid paths return the same response and documenting or fixing the actionable cause.
