Incorrectly formed path to /bin/chromium.br'

[Facundojs]

Im using chrome-aws-lambda and playwright-core just like the example. At the moment of usage of it in a serverless functions, i get the error "Error: ENOENT: no such file or directory, open '/var/task/src/scrapper/f_service/bin/chromium.br'\".
Also, i tried to add it in a layer wiht both libraries but still is failing.
This is my code:

import * as playwright from 'playwright-core';
import chromium from 'chrome-aws-lambda';

export const createBrowserContext: () => Promise<
  playwright.BrowserContext
> = async () => {
  const browser = await playwright.chromium.launch({
    args: chromium.args,
    executablePath: await chromium.executablePath',
    headless: chromium.headless,
  });
  return await browser.newContext();
};

This is how my dir looks like

AWSLambda os is the default

I had a similar issue with my function on Netlify where I needed to make sure chrome-aws-lambda as an external module.

netlify.toml

[functions.render]
  external_node_modules = ["chrome-aws-lambda"]

Perhaps you need one of the Lambda layers to make sure the module is loaded as well?

Any solution to this yet?

[Facundojs]

Yes, you have use lambda layers
In my case i zip a nodejs project for each package (Chrome anda playwright core), uploaded It as lambda layer and included It in serverless template
It should work easy

[nwaguvictor]

@Facundojs , can I get a repo example of how you used these modules in the lambda handler itself after separating the layers

[Facundojs]

Assuming you included lambda layers as we talked, you should use a code as below, you can launch browser.
In local await chromium.executablePath will return null, thats why i use || {my-local-path}

import * as playwright from 'playwright-core';
import chromium from 'chrome-aws-lambda';

export const createBrowserContext: () => Promise<playwright.BrowserContext> =
  async () => {
    const browser = await playwright.chromium.launch({
      headless: chromium.headless || true,
      executablePath:
        (await chromium.executablePath) || '/bin/google-chrome-stable',
      args: chromium.args,
    });
    return await browser.newContext({
      userAgent:
        'Mozilla/5.0 (iPhone; CPU iPhone OS 12_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.4 Mobile/15E148 Safari/604.1',
      viewport: { width: 808, height: 364 },
      screen: { width: 414, height: 896 },
      acceptDownloads: true,
      deviceScaleFactor: 3,
      isMobile: true,
      hasTouch: true,
    });
  };

You shoul use this function for every lambda.
Below, i show you an example about the aws-lambda declaration

# Basic
ValidateCredentials:
  handler: src/scrapper/validate-credentials/index.handler
  layers:
    - arn:aws:lambda:us-east-1:{id}:layer:crypto:1
    - arn:aws:lambda:us-east-1:{id}:layer:ws-layer:2 # This layer include chromium
    - arn:aws:lambda:us-east-1:{id}:layer:playwright:1 # This layer include playwright-core

Thank you a lot so far for your help. I have been able to build/deploy and attach the bundle layer. Now I’m faced with this error when I invoke my lambda cloud version  Have you encountered such issue?

I cant se correctly the file. Looks like a github problem
Try copi/paste

[nwaguvictor]

I found a solution, but the issue now is how to reference the modules inside the helper method utilized by the generate download handler
