TypeScript Type Checking Issue in HttpServer Code

pipe(
  HttpServer.router.empty,
  HttpServer.router.mountApp('/api/', API.FsaApi),
  // typescript [2345]: Argument of type 'Effect<unknown, unknown, unknown>' is not assignable to parameter of type '(a: Tag<ServerRequest, ServerRequest>) => Default<any, any>'.
  //    Type 'Effect<unknown, unknown, unknown>' provides no match for the signature '(a: Tag<ServerRequest, ServerRequest>): Default<any, any>'.
  HttpServer.middleware.make((app) =>
    pipe(
      HttpServer.request.ServerRequest,
      // typescript [2345]: Argument of type '(request: ServerRequest) => Default<E, R> | Effect<ServerResponse, RouteNotFound, Platform>' is not assignable to parameter of type '(a: ServerRequest) => Effect<ServerResponse, E, ServerRequest | R>'.
      //    Type 'Default<E, R> | Effect<ServerResponse, RouteNotFound, Platform>' is not assignable to type 'Effect<ServerResponse, E, ServerRequest | R>' with 'exactOptionalPropertyTypes: true'. Consider adding 'undefined' to the types of the target's properties.
      //      Type 'Effect<ServerResponse, RouteNotFound, Platform>' is not assignable to type 'Effect<ServerResponse, E, ServerRequest | R>' with 'exactOptionalPropertyTypes: true'. Consider adding 'undefined' to the types of the target's properties.
      //        Type 'RouteNotFound' is not assignable to type 'E'.
      //          'E' could be instantiated with an arbitrary type which could be unrelated to 'RouteNotFound'.
      Effect.flatMap((request) => {
        return request.url.startsWith("/api")
          ? app
          : pipe(
            resolvePath(request.url),
            path => HttpServer.response.file(path, { status: 200 }),
            Effect.orElse(() => new HttpServer.error.RouteNotFound({ request })),
          )
      }),
