Thank you Mikyo!!

So I'm guessing you can't add metadata to RunnableSequence? Right

querying off of invocation metadata might be a tad tough

Wondering why it would be difficult? I am not seeing any difference in setting metadata during invocation vs setting in chain (I tried both using RetrievalQA chain). Below uuid is set via invocation and application_type is set via chain

{"uuid": 1, "application_type": "question_answering"}

I am able to query the invocation metadata successfully.

I was able to add metadata to LCEL during invocation using below:

chain.invoke("Hello, How are you doing?", config={'metadata': {'uuid': 1}})

The phoenix docs mention adding metadata to the LLM chain. LCEL returns a RunnableSequence which, iiuc, does not have any option to add metadata at the chain level.

Hi Mikyo, Adding uuid in the metadata fulfils my use case. I am building a chatbot and using phoenix for observability and eval. Capturing user feedback is important part of the project. Thank you for the help!

I see an open issue #2513. Is there any workaround I can use until this is completed?
