http4s/http4s

Hello, struggling with an interesting type error while converting blaze server to jetty. Was wondering if you all have seen this before?

required: org.http4s.HttpRoutes[IO]
found: org.http4s.HttpRoutes[cats.effect.IO]

I know I've had a similar error when I first setup my authentication middleware, but can't figure out what I did to solve it. Abbreviated source code below:

object Main extends IOApp with AuthenticationMiddleware with StrictLogging {
  def httpRoutes(transactor: doobie.Transactor[IO], blocker: Blocker): HttpRoutes[IO] = HttpRoutes.of[IO] {
    case req@POST -> Root / "login" =>
      req.as[UserInfo] flatMap (user => {
        logger.info(f"authenticating user: ${user}")
        AuthService.login(user, userModel)
      })
    case req@GET -> Root / "health" => Ok() // TODO: make this a real helathcheck
  }

  override def run(args: List[String]): IO[ExitCode] =
    JettyExampleApp.resource.use(_ => IO.never).as(ExitCode.Success)

  object JettyExampleApp {
    def builder[IO[_]: ConcurrentEffect: ContextShift: Timer](blocker: Blocker): JettyBuilder[IO] = {

      JettyBuilder[IO]
        .bindHttp(8080, "0.0.0.0")
        .mountService(httpRoutes(transactor, blocker), "") // Type Error Here
    }

    def resource[IO[_]: ConcurrentEffect: ContextShift: Timer]: Resource[IO, Server] =
      for {
        blocker <- Blocker[IO]
        server <- builder[IO](blocker).resource
      } yield server
  }
}
