Langsmith trace input and output configuration

[thoffmann-artidis]

Hello! I'm working on an application using LangGraph and tracking the traces with LangSmith. However, I'm having trouble configuring LangSmith correctly. The issue is that the output displayed on LangSmith always shows the final command from the supervisor node, instead of the last message from the graph state. Is there a straightforward way to fix this?

I don't think so - we use some heuristics to determine which key to expose as the last one, and i dont think we make this configurable. I will pass along to the team though

Please, consider this, it will be more easy if we can pick which key should be picked as input/output
