puppeteer: Failed to launch the browser process!

Hi, i am using puppeteer to create PDF from HTML. The goal is to generate invoices & quotes from an html page. The API works fine, but every time i'm trying to create a PDF i encounter the following error:

[Nest] 19  - 01/17/2024, 2:55:55 PM   ERROR [ExceptionsHandler] Failed to launch the browser process!

And the only related code in my project is

import * as puppeteer from 'puppeteer';

const defaultOptions = {
  format: 'A4',
  printBackground: true,
} as puppeteer.PDFOptions;

export class PDFService {
  constructor() {}

  async pageToBuffer(path: string, options = defaultOptions) {
    const browser = await puppeteer.launch({
      headless: 'new',
      args: [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-dev-shm-usage',
      ],
    });

    const page = await browser.newPage();
    await page.goto(`${process.env.API_URL}/${path}`, {
      waitUntil: 'networkidle0',
    });
    const pdf = await page.pdf(options);
    await browser.close();
    return pdf;
  }
}

thank you @Brody for your help ! The solution was to add chrome in the dockerfile and change the PUPPETEER env variable ```FROM node:18-alpine as builder ...

try adding a nixpacks.toml to your project with this in it

[phases.setup]
    aptPkgs = [
        '...',
        'libnss3',
        'libatk1.0-0',
        'libatk-bridge2.0-0',
        'libcups2',
        'libgbm1',
        'libasound2',
        'libpangocairo-1.0-0',
        'libxss1',
        'libgtk-3-0',
        'libxshmfence1',
        'libglu1'
    ]

thank you @Brody for your help ! The solution was to add chrome in the dockerfile and change the PUPPETEER env variable

FROM node:18-alpine as builder

# Create app directory
WORKDIR /usr/src/app

# Install app dependencies
COPY package.json yarn.lock ./

RUN yarn install

RUN apk add --no-cache chromium

USER node
# Create app directory
WORKDIR /usr/src/app

# Tell Puppeteer to skip installing Chrome. We'll be using the installed package.
ENV PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium-browser
