Access violation at address - InternalReceiveINDY(ATimeout: Integer): IStompFrame;

[samuel-cruz]

Hi @danieleteti,

When I try to authenticate with an invalid user, that server returns "Stopping tcp: //127.0.0.1:49367 because Failed with SecurityException: User name [guest] or password is invalid.", The InternalReceiveINDY statement if Result.Command = 'ERROR' then, the error "Access violation at address ..." is generated, because Result is nil due to the try except that exists in

class function StompUtils.CreateFrameWithBuffer (Buf: string): IStompFrame;

  try
    ...
  except
    on EStomp do
    begin
      // ignore it
      Result: = nil;
    end;
    on e: Exception of
    begin
      Result: = nil;
      raise EStomp.Create (e.Message);
    end;
  end;

Since it is possible to identify the problem due to the exception below

---

Debugger Exception Notification

Project Project1.exe raised exception class EStomp with message 'Connection Closed Gracefully.'.

Break Continue Help

could replace the code

      if Result.Command = 'ERROR' then
        raise EStomp.Create (FormatErrorFrame (Result));

per

      if Assigned (Result) then
        if Result.Command = 'ERROR' then
          raise EStomp.Create (FormatErrorFrame (Result));

Thank you!
