TypeError: global.Set is not a constructor

[chauhanvats3]

While trying to implement a simple PGP encryption solution using your PGP library in lib folder , i run into this error :

TypeError: global.Set is not a constructor [at Object.<anonymous> (/SuiteScripts/Third Party PGP Solution/lib/openpgp.js:31665:39)]

I had been trying to use OpenPGP.js for a long time when I stumbled upon your solution. In my expedition, I always ran into the issue of not converting OpenPGP to AMD fully because of so many dependencies on Node or Browser. Your solution seems to be working because you also included the TextEncoder that I was not able to implement. But now I have ran into this issue.

Would you please help me out?

P.S. this is my Map/Reduce file :

/**

 * @NScriptType MapReduceScript

define(["N/file", "N/log", "./lib/openpgp.js"], function (file, log, openpgp) {
  /* ================== ENCRYPT FILE ======================== */

  async function encryptPGP(params) {
    const publicKeyArmored = params.publicKeyArmored;
    const inputFileContents = params.inputFileContents;
    const isText = params.isText;

    const encryptMessage = isText
      ? openpgp.message.fromText(inputFileContents)
      : openpgp.message.fromBinary(inputFileContents);

    const publicKeys = (await openpgp.key.readArmored(publicKeyArmored)).keys;

    const encryptionResult = await openpgp.encrypt({
      message: encryptMessage,
      publicKeys: publicKeys,
    });

    const encrypted = encryptionResult.data;

    return encrypted;
  }

    await Promise.all([inputFile, publicKeyFile]); //wait for the two inputFileContents and cryptoType loads to complete

    const inputFileContents = inputFile.isText
