Я работаю над POC Cloud Data Fusion и пытаюсь создать конвейер MSSQL для BigQuery. Соединение работает благодаря тому, что я могу импортировать свою схему из запроса, однако я получаю MapReduce Program "phase-1" failed с java.lang.NullPointerException: null exception
Я уже пытался использовать общий источник и приемник базы данных, как указано в этом вопросе Получение исключения нулевого указателя при отображении базы данных SQL Server в базу данных MySQL с помощью MapReduce Запрос на импорт также уже указан.
Вот полная трассировка стека
