Doesn't work with AWS Lambdas

[jovi-tsx]

Greetings! I'm currently having an issue with nanoid at my serverless stack backend + lambda function.

import { customAlphabet } from "nanoid";

export const generateNid = () => {
  const nanoid = customAlphabet(
    "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz",
    10
  );

  const nid = nanoid();

  console.log(nid);

  return nanoid() + new Date().getFullYear();
};

export const create = lambda(async (event) => {
  const body = event.body as string;
  const sale: Sale = JSON.parse(body);

  let nid = "SA" + generateNid();
  let nidExists = !!(await SaleModel.scan("nid").eq(nid).exec()).count;

  while (nidExists) {
    nid = "SA" + generateNid();
    nidExists = !!(await SaleModel.scan("nid").eq(nid).exec()).count;
  }

  return SaleModel.create({
    id: uuid.v1(),
    nid,
    ...sale
  });
});

This returns sometimes that "crypto.getRandomValues() is not a function". Other times, it will work, but it will generate only "1111111111"

You need to have Web Crypto API to use Nano ID.

We can change API if you tell us how to fix it. But I am not AWS user to give you my solution.

If I might chime in, Web Crypto API has only been available since Node 15, so do check if your lambda's Node version is 15 or later.

My env is Node 16, so this is not the problem. I am using own nodejs crypto module and it's working, if i remember correctly this error is due to the fact that getRandomValues doesn't work on server side. I used randomBytes with a custom logic for my case, but if anyone else find yourself with the same problem, maybe this comment can help. To solve this, however, I can't give you guys a proper solution since I am not an AWS expert myself
