bug: Library breaks on lambda

[spacemandev-git]

Describe the bug

I tried the same code locally as I did on aws lambda, and the lambda container could not execute. I am using a custom runtime (node v12.13) from here (https://github.com/lambci/node-custom-lambda) as the only official lambda runtimes are v8 and v10 but I don't think that's the issue.

To Reproduce Here's a sample lambda function to test the library in that I'm using

export const test: APIGatewayProxyHandler = async (_event, _context) => {
  let response = {statusCode:200, headers: {}, body: "{}"}
  //console.log(_event)
  let k2 = await V2.generateKey('public')
  let token = await V2.sign({'test': '12'}, k2)
  console.log("new token: ", token)
  let pub = crypto.createPublicKey(k2)
  let req = await V2.verify(token, pub)
  console.log("req: ", req);

  return response;
}

Expected behavior When used locally this code creates and verifies a token

Environment:

• node version: [e.g. v12.13.0]
• using aws lambda

Doesn't seem like the error is coming from paseto, but rather, node. Maybe the worker_threads module is not available in that build?

[spacemandev-git]

Going to retry with an official v12 runtime when that becomes available on lambda

Works fine in the official node12.x runtime.
