Descrizione
I use Akka = "2.5.19" and AkkaHttp = "10.1.7".
server config:
akka {
http {
parsing {
max-uri-length = 96k
max-header-value-length = 16k
}
}
}
I need to send relatively long query(more than 16k (list of ~ 300-500 uuids)). I was getting 414 status code when akka.http.parsing.max-uri-length was 8k. To fix that I've increased value up to 96k and it partially solved problem. Now server responses with (431,HttpEntity.Strict(text/plain; charset=UTF-8,HTTP header value exceeds the configured limit of 16384 characters)) which seems weird cause I send only only Auth header with short String value. To fix that I've increased akka.http.parsing.max-header-value-length up to 32k. This change has solved issue but it looks like an Akka bug.
