Hi Endre and Victor,
Thanks for getting back to me. I did understand that something was not
consumed, however I am not quite sure how this could be on my side. I am
not parsing/reading/consuming the entity directly. For that page I only
used the following directives: getFromResourceDirectory, getFromDirectory,
get, pass, complete. My typical usage of “complete” is like this:
get { ctx ⇒
async {
val y = await(x)
val z = await(y)
if (z) await(complete(StatusCodes.OK)(ctx)) else await(reject(ctx))
}
}
Is it possible to not consume the entity while only using the standard
directives?
