they have refactored their code so request now isn’t read automatically.
pls update uROWebBrokerServer.pas
as
function TROWebBrokerServer.ReadRequestStream(aRequest : TWebRequest): TStream;
...
begin
{$IFDEF DELPHIXE10UP}
aRequest.ReadTotalContent; // added
SetString(s, PAnsiChar(@aRequest.RawContent[0]), Length(aRequest.RawContent));
{$ELSE}
