Hierarchical processes with custom manager with no agent assignment on task causes an error

[andrewn3]

When you define a Hierarchical processes you don't need to specify on the task if it's assigned to an agent as you can let the manager or custom manager do this. I created a custom manager agent and assigned it to "manager=" as part of the crew definition and the left the task with no assigned agents as the manager would choose and the langtrace python sdk will fail.

This flagged this error

File "D:\Users\xxxx\crewai\xxxx\xxx\xxx.venv\Lib\site-packages*langtrace_python_sdk\instrumentation\crewai\patch.py", line 226, in _parse_tasks*
"agent": task.agent.role,**
^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'role'

i did a crude fix just to get it working e.g. "agent": task.agent.role if task.agent else None
