"Unexpected token 'o'" in type-encodings.js

[chrillek]

This code

'use strict';
const objc = require('objc');

const {
  NSURL,
  NSURLTypeIdentifierKey
} = objc;

const uti = objc.allocRef();
const error = objc.allocRef();
const fileURL = NSURL.fileURLWithPath('/Users/ck');
fileURL.getResourceValue_forKey_error(uti, NSURLTypeIdentifierKey, error);

throws this error:

Node.js v17.5.0

…/node_modules/objc/src/type-encodings.js:175
          throw new Error(`Unexpected token ${this.currentToken}`);
          ^

I think that the call to getResourceValue_forKey_error should be ok, but may of course be wrong. In that case, what should I change?
