Describe the bug and reproduction steps

I am trying to use openhands in docker headless mode with MCP. I have passed the config file via volume mapping and the tool were detected but when the llm request an action i get below error. `Unexpected error while running action: ClosedResourceError: Traceback (most recent call last): File "/app/openhands/runtime/base.py", line 350, in _handle_action observation: Observation = await self.call_tool_mcp(event) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/openhands/runtime/impl/action_execution/action_execution_client.py", line 471, in call_tool_mcp result = await call_tool_mcp_handler(mcp_clients, action) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/openhands/mcp/utils.py", line 203, in call_tool_mcp response = await matching_client.call_tool(action.name, action.arguments) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/openhands/mcp/client.py", line 127, in call_tool return await self.session.call_tool(name=tool_name, arguments=args) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/.venv/lib/python3.12/site-packages/mcp/client/session.py", line 287, in call_tool return await self.send_request( ^^^^^^^^^^^^^^^^^^^^^^^^ File "/app/.venv/lib/python3.12/site-packages/mcp/shared/session.py", line 268, in send_request await self._write_stream.send( File "/app/.venv/lib/python3.12/site-packages/anyio/streams/memory.py", line 242, in send self.send_nowait(item) File "/app/.venv/lib/python3.12/site-packages/anyio/streams/memory.py", line 211, in send_nowait raise ClosedResourceError anyio.ClosedResourceError File "/usr/local/lib/python3.12/threading.py", line 1030, in _bootstrap self._bootstrap_inner() File "/usr/local/lib/python3.12/threading.py", line 1073, in _bootstrap_inner self.run() File "/usr/local/lib/python3.12/threading.py", line 1010, in run self._target(*self._args, **self._kwargs) File "/usr/local/lib/python3.12/concurrent/futures/thread.py", line 92, in _worker work_item.run() File "/usr/local/lib/python3.12/concurrent/futures/thread.py", line 58, in run result = self.fn(*self.args, **self.kwargs) File "/app/openhands/runtime/base.py", line 307, in on_event asyncio.get_event_loop().run_until_complete(self._handle_action(event)) File "/usr/local/lib/python3.12/asyncio/base_events.py", line 674, in run_until_complete self.run_forever() File "/usr/local/lib/python3.12/asyncio/base_events.py", line 641, in run_forever self._run_once() File "/usr/local/lib/python3.12/asyncio/base_events.py", line 1987, in _run_once handle._run() File "/usr/local/lib/python3.12/asyncio/events.py", line 88, in _run self._context.run(self._callback, *self._args) File "/app/openhands/runtime/base.py", line 360, in _handle_action self.log('error', f'Unexpected error while running action: {error_message}') File "/app/openhands/runtime/base.py", line 216, in log getattr(logger, level)(message, stacklevel=2) File "/usr/local/lib/python3.12/logging/init.py", line 1568, in error self._log(ERROR, msg, args, **kwargs) File "/usr/local/lib/python3.12/logging/init.py", line 1684, in _log self.handle(record)
