✅ Have you read and understood the above guidelines?

yes

📜 What is the name of the script you are using?

changedection.io

📂 What was the exact command used to execute the script?

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

📝 Provide a clear and concise description of the issue.

Just reinstalled changedetection.io script from scratch to fix browserless not starting, and found that actually the install script itself is broken or out of date. It doesn't seem to install required browsers, although I was able to fix it post-install

⚙️ What settings are you using?

  • Default Settings
  • Advanced Settings

🖥️ Which Linux distribution are you using?

Debian 12

🔄 Steps to reproduce the issue.

  • Install the lxc default/advanced (doesn't matter)
  • Browserless fails to start due to missing browser binaries

❌ Paste the full error output (if available).

Initial error post-install is:

Feb 10 10:46:35 watch browserless[21112]: Unhandled Rejection at: Promise {
Feb 10 10:46:35 watch browserless[21112]:   <rejected> Error: Couldn't load route "/content?(/),/chromium/content?(/)" due to missing browser binary for "ChromiumCDP".

🖼️ Additional context (optional).

It looks like this was fixed in https://github.com/community-scripts/ProxmoxVE/pull/1027 for the update script only? I'm able to manually execute (from that patch):

/opt/browserless/node_modules/playwright-core/cli.js install --with-deps &>/dev/null
/opt/browserless/node_modules/playwright-core/cli.js install --force chrome &>/dev/null
/opt/browserless/node_modules/playwright-core/cli.js install chromium firefox webkit &>/dev/null

It still doesn't start due to:

Feb 10 11:16:28 changedetection browserless[1880]: Unhandled Rejection at: Promise {
Feb 10 11:16:28 changedetection browserless[1880]:   <rejected> Error: Couldn't load route "/edge/content?(/)" due to missing browser binary for "EdgeCDP".

I was able to fix this then by running manuall:

/opt/browserless/node_modules/playwright-core/cli.js install --force msedge

Then browserless appears to be happy. So appears the install script needs updates and possibly aligning with the updater?

Sorry, but I can't see the fix. I tried updating my lxc but the problem is still there. What am I missing?

It's broken on my end the same way as in https://github.com/community-scripts/ProxmoxVE/issues/2304 as well.

Here is a full log of running the update again: https://bin.linux.pizza/?d70e93064124e5e4#CierrTiFY7uVm7pSyr6kqjsEziLUVUasqLpo2K4nGnWF

ChangeDetection displays:

Maybe this is the issue? browserless.service: Failed to locate executable /opt/browserless/start.sh: No such file or directory (See the last log above.)
