Java - генерация XML - пустой файл

1 голос
/ 17 апреля 2019

У меня есть веб-сервис Java, который запускается для интеграции через обмен файлами XML с ERP, он прекрасно работал со дня его разработки. Вчера утром он начал генерировать пустые файлы XML без каких-либо изменений в своем исходном коде. Любой сделанный запрос генерирует пустые файлы, что делает невозможным взаимодействие между платформами. Анализируя журнал сервера, появляется следующая ошибка

Я уже пытался повторно развернуть его, поскольку не было никаких изменений в его коде, но без успеха. Когда я запускаю приложение локально, оно работает нормально ...

Ожидаемый вывод должен быть XML-файл с этой структурой
