I have a typescript file with imports eg:

util.ts file

import { protractor } from 'protractor'

export const waitForFile = async () => {
 protractor.promise....
 return await ''
}

Now helper.js file

const getUtilFunction = (func) => {
  const { register } = require('ts-node');
  const { compilerOptions } = require('./tsconfig.json');
  register({ compilerOptions });
  const result = require('./utils.ts');
  return result[func];
};

const waitTillReportGenerated = async () => {
  const waitForFileToDownload = getUtilFunction('waitForFileToDownload');
  const file = await waitForFileToDownload('./result/result.js', 60000);
  console.log(file);
}

However when we call the helper.js function it throws error that protractor is undefined. Can someone please help me with this?
