Summary

Problem: The error logging in _send_event() and _send_bash_event() used a literal string "error_sending_event:{event}" instead of an f-string. This meant {event} was logged literally instead of the actual event data.

About Multi-Architecture Support

  • Each variant tag (e.g., d47c260-python) is a multi-arch manifest supporting both amd64 and arm64
  • Docker automatically pulls the correct architecture for your platform
  • Individual architecture tags (e.g., d47c260-python-amd64) are also available if needed

Fix non-JSON logging in sockets.py and state.py
fdd3fc1 
- Fix literal string '{event}' in error logs (sockets.py lines 145, 163)
  The string was not an f-string, so {event} was logged literally instead
  of the actual event data. Changed to use %r format which calls repr()
  to get useful debugging info (class name, id, source, timestamp).

- Fix model_dump() returning non-JSON-serializable objects (state.py)
  The model_dump() method returns Python objects like UUID and enums
  that appear as repr strings in logs (e.g., UUID('...'), <Enum.VALUE>).
  Changed to use model_dump(mode='json') wrapped in json.dumps() for
  proper JSON-serializable output.

I've completed the requested changes:

Summary

  1. Reverted Fix 2 (state.py changes): Removed the json.dumps() changes from openhands-sdk/openhands/sdk/conversation/state.py by checking out the main version of that file.

  2. Updated the PR description: Updated PR Fix useless logging in sockets.py #1679 to remove references to Fix 2. The PR now only contains Fix 1 (the sockets.py literal string fix).

  3. CI passes: All key tests have passed:

    • ✅ agent-server-tests
    • ✅ sdk-tests
    • ✅ tools-tests
    • ✅ cross-tests
    • ✅ pre-commit
    • ✅ Check OpenAPI Schema

Final Changes

The PR now only contains the fix for the literal string logging issue in sockets.py:

-logger.exception("error_sending_event:{event}", stack_info=True)
+logger.exception("error_sending_event: %r", event, stack_info=True)

This ensures that error logs now include the actual event data (using %r for repr formatting) instead of the literal string {event}.

The fix correctly addresses the logging bug by using proper printf-style formatting with %r. Good catch on adding the space after the colon and making the bash event message more specific.
