changedetection - Playwright-content-fetcher not working

[kossidts]

I encountered an issue with the Playwright-content-fetcher not working, and upon investigation, it seems related to the browserless service failing to start.

Running systemctl status browserless returned:

× browserless.service - browserless service
     Loaded: loaded (/etc/systemd/system/browserless.service; enabled; preset: enabled)
     Active: failed (Result: exit-code) since Sun 2024-09-01 17:55:12 CEST; 1s ago
   Duration: 1ms

Sep 01 17:55:12 changedetectionio systemd[1]: browserless.service: Failed with result 'exit-code'.

The /etc/systemd/system/browserless.service has this configuration:

[Unit]
Description=browserless service
After=network.target
[Service]
Environment=APP_DIR=/opt/browserless
Environment=PLAYWRIGHT_BROWSERS_PATH=/opt/browserless
Environment=CONNECTION_TIMEOUT=60000
Environment=HOST=127.0.0.1
Environment=LANG="C.UTF-8"
Environment=NODE_ENV=production
Environment=PORT=3000
Environment=WORKSPACE_DIR=/opt/browserless/workspace
WorkingDirectory=/opt/browserless
ExecStart=/opt/browserless/start.sh
SyslogIdentifier=browserless
[Install]
WantedBy=default.target

But the structure of /opt/browserless looks like:

.
├── assets
├── bin
├── build
├── CHANGELOG.md
├── docker
├── extensions
├── external
├── fonts

├── scripts

│       └── test.sh
├── src
├── static
└── tsconfig.json

the start.sh file is located under scripts, so updated the service file accordingly

ExecStart=/opt/browserless/scripts/start.sh

This results in

Has anyone else encountered this issue, or does anyone have suggestions on resolving it?

Same issue here, no idea how to make it work with Browserless v2 so I downgraded existing installation to Browserless v1 using #2262 (comment) and reverted changes to changedetection.service made in 72dfc20 , then it seems to be fine.
