Hi Phoenix Support, I have a question in using phoenix for agent tracing. I’m tracing my agent application in Phoenix, and each node exchanges input and output as a JSON-formatted state. Phoenix is tracing that—but does Phoenix have any functionality like pretty print or a typical JSON viewer, where I can expand and collapse each key? Or is that not supported?

Hello, everyone. I have a question about tracing in Phoenix. I’m using langgraph and currently executing my graph asynchronously using graph.astream(). I was wondering how I can enable or capture tracing in Phoenix while the graph is running in streaming mode. Any guidance would be appreciated.

async for chunk in agent_graph.astream(base_state, stream_mode="messages"):
            if chunk[1]["langgraph_node"] == "node_response":
                yield chunk[0].content

I get an error like below.

packages/langchain_core/runnables/config.py", line 616, in run_in_executor return await asyncio.get_running_loop().run_in_executor( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ...<2 lines>... ) ^ asyncio.exceptions.CancelledError: <object object at 0x1141d1860>
