Hey there and thanks for sharing! I replied on Reddit but figured it may be better to post here.

I've been struggling to get SK + LC to work together nicely, particularly when trying to create an API Endpoint (/api/chat). I can get the LC chain.call() response logged out in the server with the OpenAI response, but I haven't figured out how to return a proper Response back to the SK frontend. I've read that I may need a ReadableStream instead, but not sure.

I've used the @microsoft/fetch-event-source package in the frontend with its onmessage(event) listener, but I can't seem to get any event to trigger. If you sort out how to properly return a Response from the server that contains the ChainValues, please let me know!
