THEN Replace FunctionCallingAgentWorker with the newer Workflow-based agent API. Use AgentWorkflow or the new FunctionAgent class from llama_index versions >=0.11.2. These support streaming natively. Refer to the official docs for migration: https://docs.llamaindex.ai/en/stable/understanding/agent/streaming/.

# Old (broken):
agent = FunctionCallingAgentWorker.from_tools(tools).as_agent()
agent.stream_chat("Hello!")  # Fails

# New (working):
from llama_index.core.agent import AgentWorkflow
agent = AgentWorkflow.from_tools(tools)
response = agent.stream_chat("Hello!")
for chunk in response:
    print(chunk.delta, end="")
