node.js - How to Fix Could not find browser revision 756035

Question

I am using puppeteer to execute some test cases in Docker and I get this below error:

"before all" hook: codeceptjs.beforeSuite for "Validate_onbord_broker_business": Could not find browser revision 756035. Run "npm install" or "yarn install" to download a browser binary. at ChromeLauncher.launch (node_modules/puppeteer/lib/Launcher.js:59:23) at async Puppeteer._startBrowser (node_modules/codeceptjs/lib/helper/Puppeteer.js:512:22)

And this is the Dockerfile I am using:

# Use whatever version you are running locally (see node -v)
FROM node:12.18

WORKDIR /app

RUN  apt-get update 
     && apt-get install -y wget gnupg ca-certificates 
     && wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - 
     && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' 
     && apt-get update 
     && apt-get install -y google-chrome-stable 
     && rm -rf /var/lib/apt/lists/* 
     && wget --quiet https://raw.githubusercontent.com/vishnubob/wait-for-it/master/wait-for-it.sh -O /usr/sbin/wait-for-it.sh 
     && chmod +x /usr/sbin/wait-for-it.sh

# Install dependencies (you are already in /app)
COPY package.json package-lock.json ./
# RUN npm ci
RUN npm install
ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true
RUN npm install codeceptjs puppeteer
COPY . /app

RUN pwd
RUN ls


# RUN npx codeceptjs init


RUN npx codeceptjs run 

# CMD ["npm", "start"]

Can someone please help me what is going wrong?

I think the problem is that you're skipping downloading a version of chromium when you install your dependencies: ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true. Puppeteer is only guaranteed to work with the bundled version of chromium and it's generally a bad idea to use some other version of chromium.

Based on your comments on your post, I'm guessing that the reason you're not using the bundled version of Chromium is because you're having "fun" with dependencies. These can be manually installed using apt - here are the dependencies which are installed by the official puppeteer dockerfile:

apt-get -y install xvfb gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 
      libdbus-1-3 libexpat1 libfontconfig1 libgbm1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 
      libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 
      libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 
      libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget

I think this is the updated Dockerfile - let me know if it works because I can't test it without the rest of your code!
