如何在使用 Amplify 创建的 AWS lambda function 上使用 chrome-aws-lambda

Question

I'm trying to create this lambda function in AWS using Amplify however when I try to launch the chromium the lambda function does not return any value and the function end up timing up:

"errorMessage": "2020-12-09T02:56:56.210Z 57402f8e-9fb2-4341-837d-bdf2ee6e9262 Task timed out after 25.57 seconds" I add the Layer as suggested by @James Shapiro, now I'm getting a URL return for the chromium but it still not launching it:

This is my function:

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

exports.handler = async (event, context) => {

    const pageToScreenshot = "https://www.google.com"

    console.log('page:', pageToScreenshot);

    if (!pageToScreenshot) return {
        statusCode: 400,
        body: JSON.stringify({ message: 'Page URL not defined' })
    }

    console.log('launch:');
    console.log('chromium.args:', chromium.args);
    console.log('chromium.defaultViewport:', chromium.defaultViewport);
    console.log('chromium.headless:', chromium.headless);

    const executablePath = await chromium.executablePath;

    const browser = await chromium.puppeteer.launch({
        args: chromium.args,
        defaultViewport: chromium.defaultViewport,
        executablePath,
        headless: chromium.headless,
    });
    console.log('page:');

    const page = await browser.newPage();
    console.log('goto:');

    await page.goto(pageToScreenshot, { waitUntil: 'networkidle2' });
    console.log('screenshot:');

    const screenshot = await page.screenshot({ encoding: 'binary' });
    console.log('close:');

    await browser.close();
    console.log('response:');

    return {
        statusCode: 200,
        body: JSON.stringify({
            message: `Complete screenshot of ${pageToScreenshot}`,
            buffer: screenshot
        })
    }

}

This is the dependencies:

{
  "name": "snapshot31baa866",
  "version": "2.0.0",
  "description": "Lambda function generated by Amplify",
  "main": "index.js",
  "license": "Apache-2.0",
  "dependencies": {

    "puppeteer-core": "^5.5.0"
  }
}

Answer 1

Have you tried installing a chrome-aws-lambda layer and then adding it to your function? See the instructions here in the "AWS Lambda Layer" section.

Answer 2

I had to increase the memory and time out of the lambda function, however, I don't think it would work without James Shapiro's help, thanks.
