Incompatible Router Types

I am working on a trpc implementation for sveltekit. I attached a screenshot of the createContext function, the fetchRequestHandlers, and the client. Everything works but I am getting a typescript error that is breaking auto-complete. I will comment the error below.

I managed to resolve this by un-installing and re-installing the @trpc/server and @trpc/client packages
