Incorrect type for createContext params for trpc-server

[paymog]

Which middleware has the bug?

@hono/trpc-server

What version of the middleware?

^0.3.4

What version of Hono are you using?

^4.6.15

What runtime/platform is your app running on? (with version if possible)

node 20

What steps can reproduce the bug?

I'm using trpcServer like so

app.use(
  "/trpc/*",
  trpcServer({
    router: appRouter,
    createContext: (opts, c) => createContext(opts),
    onError({ error }) {
      console.error(error);
    },
  }),
);

I have the trpc createContext function defined like so

export const createContext = async (c: CreateNextContextOptions) => {
///stuff
}

It seems that the opts passed in from the trpc-server package is of type incompatible with the CreateNextContextOptions param as documented here

What is the expected behavior?

I expect the types for opts to match the types for the createContext of trpc.

What do you see instead?

Type types do not match

src/main.ts:36:47 - error TS2345: Argument of type 'FetchCreateContextFnOptions' is not assignable to parameter of type 'CreateNextContextOptions'.
  Property 'res' is missing in type 'FetchCreateContextFnOptions' but required in type 'CreateNextContextOptions'.

36     createContext: (opts, c) => createContext(opts),
                                                 ~~~~
