Hi Oleg,
There is a *getContentLength* method in *AbstractClassicEntityProducer* which
is final and can’t be overwritten (see below) and always return -1 and also
there is no variable which holds content length to overwrite it. If we add
ContentLength header to request builder we get an exception as below. Is
there any other way to generate contentLength.
@Override
public final long getContentLength() {
return -1;
}
*Exception Thrown*
Caused by: org.apache.hc.core5.http.ProtocolException: Content-Length
header already present
