WebResourceResponseViewGetContentCompleted returning errorCode -32000 (0xFFFF8300)

hello..

I'm using MiniBrowser demo and I got no return in one specific request of a webpage.

at the event:

procedure TMiniBrowserFrm.WVBrowser1WebResourceResponseViewGetContentCompleted(
  Sender: TObject; aErrorCode: HRESULT; const aContents: IStream;
  aResourceID: Integer);
var
  TempOLEStream : TOLEStream;
begin
  TempOLEStream := nil;
  try
    // Copy the resource contents into FResourceContents
    // The "Save resource as..." menu option will save FResourceContents in an HTML file.
    if succeeded(aErrorCode) and assigned(aContents) then
      begin
        TempOLEStream          := TOLEStream.Create(aContents);
        TempOLEStream.Position := 0;

        if (TempOLEStream.Size > 0) then
          begin
            SetLength(FResourceContents, TempOLEStream.Size);
            TempOLEStream.Read(FResourceContents, TempOLEStream.Size);
          end;
      end;
  finally
    if assigned(TempOLEStream) then
      FreeAndNil(TempOLEStream);
  end;
end;

the variable aErrorCode returns -32000, and aContents = nil...

I tested to debug the event in Firefox and the same link returns a valid json as content...

In the WVBrowser1WebResourceResponseReceived the header is all ok, even the length of the content.

do you have any idea about this error?
