Hello, does anyone have experience with receiving invalid JSON objects using call.receive<T>() ?
Currently my server returns 500 Internal Server Error , I would like to return 400 Bad Request in some general reusable fashion. I can't seem to find any resources regarding this topic, Thanks!

Use Status Pages to intercept the exception in your stack trace and change the response code

install(StatusPages) {
    exception<Exception> { cause ->
        call.respond(HttpStatusCode.BadRequest)
    }
}

I'm doing the same as @sultanofcardio

install(StatusPages) {
    exception<JsonSyntaxException> {
      call.respond(HttpStatusCode.BadRequest, Error(it.message))
    }
  }
