No matching WebSocket route handler for after updating docker images

[42Craft]

After updating my Docker images to the latest version for browserless and changedetection, my setup has stopped functioning. I am seeking guidance on how to resolve this issue. Can someone point me in the right direction? I do not entirely understand how an update could have lead to my issue.

Logs

Browserless:

browserless.io:server:trace  Handling inbound WebSocket request on "/?stealth=1&--disable-web-security=true&blockAds=true" +0ms
browserless.io:server:error  No matching WebSocket route handler for "http://0.0.0.0:3000/?blockAds=true&launch=%7B%22stealth%22%3Atrue%2C%22args%22%3A%5B%22--disable-web-security%3Dtrue%22%5D%7D" +0ms

Change Detection:

Exception: WebSocket error: ws://playwright-chrome:3000/ 404 Not Found Not Found

Docker Compose Configuration

version: '3.2'
services:
  changedetection:
    container_name: changedetection
    image: ghcr.io/dgtlmoon/changedetection.io:latest
    hostname: changedetection

      - /volume2/docker/containers/changedetection:/datastore

      - SCREEN_HEIGHT=1024
      - SCREEN_DEPTH=16
      - ENABLE_DEBUGGER=false
      - TIMEOUT=60000
      - CONCURRENT=10
    dns:

    networks:

networks:
  app_net:  
    ipam:  
      driver: default  
      config:  
        - subnet: "<REDACTED>"

Steps to Reproduce

1. Update Docker images for browserless and changedetection to the latest versions.
2. Deploy the updated containers using the provided Docker Compose configuration.
3. Attempt to use the changedetection service.

Expected Behavior

The services should function normally, with changedetection able to connect to the playwright-chrome service without errors.

Actual Behavior

The changedetection service logs indicate a WebSocket error (404 Not Found) when checking websites for differences.

Any insights or suggestions would be greatly appreciated. Thank you!

• you have a very very non standard network setup which is outside our default example
• you should use our sockpuppet browser instead

[42Craft]

Thank you for your suggestions. Sockpuppet browser looks interesting and looks quite new. Is it recommended to use this instead?

[42Craft]

I fixed it! It has to do with a change in browserless.

As of browserless v2.2.0, for the ghcr.io/browserless/chrome image, the /chrome endpoint must be added to the URL, so e.g.:
PLAYWRIGHT_DRIVER_URL=ws://browserless-chrome:3000/chrome?launch={"headless":false}

Thank you! I've been dealing with this for a few months now and completely wrote off Change Detection playwright support. This fixed it instantly!

Always just go back to the default docker-compose.yml thats in this repo.
