ClassCassException when using HandlerAspect and Path parameters. #3141
Description
Describe the bug
We are getting ClassCastExceptions when using a route with Path paramters, and a middleware that adds context.
class zio.http.Request cannot be cast to class scala.Tuple2 (zio.http.Request and scala.Tuple2 are in unnamed module of loader 'app')
Tuple2 is increasing if we add more path params
To Reproduce
Run this snipped
import zio.http._
import zio._
import scala.annotation.nowarn
object Reproducer extends ZIOAppDefault {
case class WebSession(id: Int)
def maybeWebSession: HandlerAspect[Any, Option[WebSession]] =
HandlerAspect.interceptIncomingHandler(
Handler.fromFunctionZIO[Request] { req =>
ZIO.succeed((req, None))
}
)
@nowarn("msg=dead code following this construct")
override def run: ZIO[Any, Any, Any] = {
// fails at Handler.scala line 57 with
val route = Method.GET / "base" / string("1") -> handler((a: String, req: Request) => {
withContext((c: Option[WebSession]) => {
ZIO.logInfo("Hello").as(Response.ok)
})
}) @@ maybeWebSession
(for {
port <- Server.install(Routes(route))
_ <- ZIO.logInfo(s"Installed on port " + port)
_ <- ZIO.never
} yield ()).provide(Server.default)
}
}run: curl -v 127.0.0.1:8080/base/1
Expected behaviour
Log Hello and return 200 Ok
Additional context
Same error in scala 2 and 3.
Using Intellij breakpoints on all exception, it stops at Handler.scala - line 57
