akka/akka

Hi Akka experts, I have a question regarding akka-http server. I am trying to handle a request in one of my route and if I do not pass any Content-type in the request by default akka is setting it to application/octet-stream.

Please find my implementation below: -

package com.example
import akka.actor.typed.ActorSystem
import akka.actor.typed.scaladsl.Behaviors
import akka.http.scaladsl.Http
import akka.http.scaladsl.model.{ContentTypes, HttpEntity}
import akka.http.scaladsl.server.Directives._
import akka.http.scaladsl.server.Route
import scala.io.StdIn
object HttpServerContentTypeTest {
  def main(args: Array[String]): Unit = {
    implicit val actorSystem = ActorSystem(Behaviors.empty, "RandomNumbers")
    implicit val executionContext = actorSystem.executionContext
    val route = path("proxy"){
      Route { context =>
        println(context.request.entity.contentType)
        context.complete(HttpEntity(ContentTypes.`text/plain(UTF-8)`, ""))
      }
    }
    val bindingFuture = Http().newServerAt("localhost", 9000).bind(route)
    // press any key to stop the server
    StdIn.readLine()
    bindingFuture.flatMap(_.unbind()).onComplete(_ => actorSystem.terminate())
  }
}

I tested this via Postman(please find screenshot attached showing the headers and the body used). I am trying to send a post request with non-empty request body. Also I am not setting Content-type header.

I want that akka-http server internally does not set header Content-type. Is there a way to disable this default behavior?
