tRPC error in app Router (undefined headers)

I use the tRPC file structure from Jack Herringtons video I added clerk auth for protected routes and set the create Context in the route handler: 
createContext: () => createTRPCContext(req),



interface AuthContext {
  auth: SignedInAuthObject | SignedOutAuthObject
}
const createInnerTRPCContext = async ({ auth }: AuthContext) => {
  return {
    auth,
  }
}

export const createTRPCContext = async (req: NextRequest) => {
  return await createInnerTRPCContext({ auth: getAuth(req) })
}

export type Context = trpc.inferAsyncReturnType<typeof createTRPCContext>

export const t = initTRPC.context<typeof createTRPCContext>().create({
  transformer: superjson,
  errorFormatter({ shape, error }) {
    return {
      ...shape,
      data: {
        ...shape.data,
        zodError: error.cause instanceof ZodError ? error.cause.flatten() : null,
      },
    }
  },
})

export const createTRPCRouter = t.router
createContext: () => createTRPCContext(req),



interface AuthContext {
  auth: SignedInAuthObject | SignedOutAuthObject
}
const createInnerTRPCContext = async ({ auth }: AuthContext) => {
  return {
    auth,
  }
}

export const createTRPCContext = async (req: NextRequest) => {
  return await createInnerTRPCContext({ auth: getAuth(req) })
}

export type Context = trpc.inferAsyncReturnType<typeof createTRPCContext>

export const t = initTRPC.context<typeof createTRPCContext>().create({
  transformer: superjson,
  errorFormatter({ shape, error }) {
    return {
      ...shape,
      data: {
        ...shape.data,
        zodError: error.cause instanceof ZodError ? error.cause.flatten() : null,
      },
    }
  },
})

export const createTRPCRouter = t.router
but this results in the following error: 
 error TypeError: Cannot read properties of undefined (reading 'headers')
