Change Detection LXC Installs but Browserless service cannot start

A clear and concise description of the issue.

After an update, my change detection lxc stopped working for all watches that used the Playwright fetch method. I erased the container and started over. When I run

systemctl status browserless.service

I see:

Dec 27 23:47:29 changedetection browserless[1175]: Unhandled Rejection at: Promise {

Dec 27 23:47:29 changedetection browserless[1175]: 2023-12-28T06:47:29.207Z browserless:index.js Process is finished, exiting

I installed the browsers manually with

npm run install:dev

and then I can manually start browerless with the start.sh script in opt/browserless and then changedetection and the watches that rely on the playwright work as they should.

However, even though after the browsers are installed and I can manually start browserless, the service reports the same error on start.

Which Linux distribution are you employing?

Debian 12

If relevant, including screenshots or a code block can be helpful in clarifying the issue.

No response

Please provide detailed steps to reproduce the issue.

Use install script from website:

bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/changedetection.sh)"

Setup a new watch with the the playwright fetch method and you should always see this error:
"WebSocket error: connect ECONNREFUSED 127.0.0.1:3000 "

then if you check the browserless service, you should see what I recorded above.

My primary focus revolves around the development of application LXCs, and I'm not specialized in providing support for operational issues that may arise with these applications.

Admittedly, I know nothing about how this application works, never used it.

It suggests that the browserless service is encountering an error when trying to load the specified route "/content" because it can't find the required browser ("CDPChromium").

I'm going to send this issue to Discussions. Hopefully someone will advise with a solution.

The browserless service is running.

Makes sense.

Hi the problem is they have recently released a new major version of Browserless. Install the old version instead.

For an existing install, just run this:
mv /opt/browserless /opt/browserless_old
git clone -b v1 https://github.com/browserless/chrome /opt/browserless
npm install --prefix /opt/browserless
npm run build --prefix /opt/browserless
npm prune production --prefix /opt/browserless

Then restart the browserless service with service browserless restart. It works now

Thanks!

@tteck @pieslinger moving forward we should find a way to get browserless V2 working. There may be security vulnerabilities in older versions

@lukyjay did you find a way to resolve this issue with latest? I'm not to sure, but I think I might have the same issue: #3822
