I don't think he tried to dock an AI aircraft, otherwise he wouldn't see that message (meaning he's using GSX).
SODE jetways operated from GSX don't use the [exits] section of the airplane.cfg file, but rather the GSX door configuration, which is way more precise. But of course, this assumes you configured this airplane correctly in GSX, with all its doors in the proper place.
You don't say which aircraft is, so I guess it's an unsupported one, so you must create a GSX configuration using the include airplane configuration editor, in order to use it with GSX.
