Version: OpenClaw 2026.3.28 (f9b1079)

What I expected: After enabling browser support and restarting the gateway, openclaw browser status should work and the gateway should expose browser.request.

What happened: openclaw browser status fails with:

GatewayClientRequestError: unknown method: browser.request

What I verified:

• browser.enabled = true • browser plugin is loaded • openclaw plugins inspect browser shows it declares: • service: browser-control • method: browser.request • gateway was restarted cleanly: • openclaw gateway stop • pkill -f openclaw • openclaw gateway start • still same error

Setup: • macOS • Brave configured as browser executable • Brave existing-session profile configured • issue occurs even before attach succeeds, because gateway method is missing entirely

Repro:

openclaw browser status

Actual result:

GatewayClientRequestError: unknown method: browser.request

Error Message

GatewayClientRequestError: unknown method: browser.request

Root Cause

Setup: • macOS • Brave configured as browser executable • Brave existing-session profile configured • issue occurs even before attach succeeds, because gateway method is missing entirely

Fix Plan

To resolve the GatewayClientRequestError: unknown method: browser.request issue, follow these steps:

  1. Verify Browser Plugin Configuration:

    • Ensure that the browser plugin is correctly configured and loaded.
    • Check the openclaw configuration file for any typos or incorrect settings.
  2. Register Browser Request Method:

    • In the openclaw gateway code, locate the section where methods are registered.
    • Add or verify the registration of the browser.request method.

Example code snippet (hypothetical, as actual code is not provided):

# Assuming a Python-based implementation
from openclaw.gateway import Gateway

# Register the browser.request method
gateway = Gateway()
gateway.register_method('browser.request', browser_request_handler)
  1. Implement Browser Request Handler:
    • Define a handler function for the browser.request method.
    • This function should handle the browser request logic.

Example code snippet:

def browser_request_handler(request):
    # Handle the browser request
    # This is a placeholder, actual implementation depends on the requirements
    return {"status": "success"}
  1. Restart OpenClaw Gateway:
    • After making the necessary changes, restart the openclaw gateway to apply the updates.
    • Use the commands provided in the issue description:

openclaw gateway stop pkill -f openclaw openclaw gateway start


### Verification
To verify that the fix worked:

1. Run `openclaw browser status` again.
2. Check if the `GatewayClientRequestError: unknown method: browser.request` error is resolved.
3. Verify that the `browser.request` method is exposed and functional.

### Extra Tips
- Ensure that the `browser` plugin is correctly loaded and configured.
- Check the `openclaw` logs for any errors or warnings related to the `browser.request` method.
- If issues persist, try debugging the `browser_request_handler` function to identify any problems.
