hermes - 💡(How to fix) Fix [Weixin] File/image sending fails with asyncio timeout error [2 comments, 3 participants]

Bug Description: When sending images/files to WeChat via the send_message tool, if the Gateway is running, the following error

Timeout context manager should be used inside a task
Task <Task pending name='Task-2844' coro=<_send_to_platform() running at
home/*/hermes-agent/tools/send_message_tool.py:507> got Future attached to a different loop

Plain text messages are sent successfully, but messages with media (images, files) fail.

Root Cause The send_weixin_direct function in gateway/platforms/weixin.py attempts to reuse the aiohttp.ClientSession from the already-connected adapter in _LIVE_ADAPTERS.

When send_message tool is called from CLI or cron, _run_async creates a separate event loop (loop B) in a new thread, while the live adapter's session is bound to the Gateway's main event loop (loop A). Cross-loop operations on the aiohttp session cause Python 3.11+'s asyncio.timeout() to raise an exception. Environment

• Hermes Agent version: latest
• Python version: 3.11+
• aiohttp version: 3.10+
• Platform: Weixin Related Issues

Questions for Maintainers

1. This bug makes Weixin file/image sending completely unusable (text works fine, but media always fails with Timeout context manager should be used inside a task). Over 10 contributors have submitted PRs for this issue, yet none have been merged — we're hoping to understand if there are any ongoing technical considerations or concerns that have made it difficult to land a fix.
2. Is there an existing plan or preferred approach to resolve this? We'd love to know if there's a direction the maintainers favor (e.g., detecting loop mismatch and falling back to a fresh session, vs. scheduling sends onto the adapter's loop with run_coroutine_threadsafe).
