Yuan Tang 1a044ef894 fix: Raise exception when tool call result is None (#1253) ... # What does this PR do? When there are issues with the tool call function, an exception is raised but the error message is not informative. This adds a clearer message to tell users to check their functions. ``` Traceback (most recent call last): File "/Users/phayes/projects/llama-stack/llama-stack/llama_stack/distribution/server/server.py", line 208, in sse_generator async for item in event_gen: File "/Users/phayes/projects/llama-stack/llama-stack/llama_stack/providers/inline/agents/meta_reference/agents.py", line 165, in _create_agent_turn_streaming async for event in agent.create_and_execute_turn(request): File "/Users/phayes/projects/llama-stack/llama-stack/llama_stack/providers/inline/agents/meta_reference/agent_instance.py", line 197, in create_and_execute_turn async for chunk in self.run( File "/Users/phayes/projects/llama-stack/llama-stack/llama_stack/providers/inline/agents/meta_reference/agent_instance.py", line 389, in run async for res in self._run( File "/Users/phayes/projects/llama-stack/llama-stack/llama_stack/providers/inline/agents/meta_reference/agent_instance.py", line 811, in _run content=tool_result.content, AttributeError: 'NoneType' object has no attribute 'content' ``` ## Test Plan Ran the same script and exception is raised with clearer error message.
