Cannot find module '/app/node_modules/puppeteer-core/lib/cjs/puppeteer/common/Browser

Question

I was trying to run Puppeteer on an AWS Lambda function and got the following error.

Error: Error: Cannot find module '/app/node_modules/puppeteer-core/lib/cjs/puppeteer/common/Browser'

This has happened on both locally and when I deploy it to AWS as well.

The code:

const chromium = require("chrome-aws-lambda");

const generateImg = async (reviewId) => {
  let browser = null;
  let result = null;

  try {
    const executablePath = await chromium.executablePath;
    browser = await chromium.puppeteer.launch({
      args: chromium.args,
      executablePath: executablePath,
      headless: chromium.headless,
    });

    const page = await browser.newPage();
    await page.goto(
      "https://www.example.com"
    );

    result = await page.screenshot();
  } catch (error) {
    console.error("Error:", error);
  } finally {
    if (browser !== null) {
      await browser.close();
    }
  }

  return result;
};
