Hello! I've implemented trpc to my nextjs 14 app router project, along with trpc socket subscriptions. I recently started making use of trpc context and implemented an asyncrhinous check to my session handler in order to append session information to my trpc context. This all works fine for the majority of my trpc functionality (non websocket stuff), however my clients are unable to establish a websocket connection to the server as every time the initial upgrade request is sent, the server 500 errors due to the added context initialisation.
The error seems to be caused because some server component functionality ( cookies() ) is called during the call to fetch session information during context initialisation for the socket. Why does this cause an error when initliasing the trpc websocket client and not when making a standard trpc request?
