Problem:

The error is coming from the following file:

`.../electron/app/node_modules/handbrake-js/dist/index.cjs`

At this current block of code:

function getModulePaths (fileURL) {
  const __filename = url.fileURLToPath(fileURL);
  const __dirname = path.dirname(__filename);
  return { __filename, __dirname }
}

const { __dirname: __dirname$1 } = getModulePaths((typeof document === 'undefined' ? require('u' + 'rl').pathToFileURL(__filename).href : (document.currentScript && document.currentScript.src || new URL('index.cjs', document.baseURI).href)));

The url to the HandbrakeCLI binary doesn't seem to resolve as being of type file:// when the package is installed in an electron environment, thus being blocked at the following function (in Object.fileURLToPath (node:internal/url:1424:11)):

function fileURLToPath(path) {
  if (typeof path === 'string')
    path = new URL(path);
  else if (!isURLInstance(path))
    throw new ERR_INVALID_ARG_TYPE('path', ['string', 'URL'], path);
  if (path.protocol === 'electron:')
    return 'electron';
  if (path.protocol !== 'file:')
    throw new ERR_INVALID_URL_SCHEME('file');
  return isWindows ? getPathFromURLWin32(path) : getPathFromURLPosix(path);
}

setup:

• process.platform = darwin
• process.arch = arm64
• node version: v19.1.0
• "electron": "^21.3.1"

Any tips to get the URL right would be greately appreciated.
