i am running a puppeteer script and it seems i have to declare a mailosaur stack for me to proceed with my code. I am running a node.js script in aws cloudwatch. here is me defining the stack, and the code follows suit.

const synthetics = require('Synthetics');
const MailosaurClient = require('mailosaur');
const log = require('SyntheticsLogger');
const puppeteer = require('puppeteer-core');
const url = require('url');
const { v4: uuidv4 } = require('uuid');

await synthetics.executeStep('Assert the email was received', async function () {
      const mailosaur = new MailosaurClient(`${process.env.MAILOSAUR_API_KEY}`);
      const serverId = ''
      const serverDomain = `${serverId}.mailosaur.net`

      const searchCriteria = {
          sentTo: `${patientEmailAddress}@${serverDomain}`
      }

      const message = await mailosaur.messages.get(serverId, searchCriteria)
      const dom = new JSDOM(message.html.body);
      const el = dom.window.document.querySelector('p.em_defaultlink > a');
      target = el.href;
    });

 

the error reads
