Добрый день,
Столкнулись с ошибкой при загрузке файлов через компонент fileStorageUploadField. В процессе анализа обнаружили другую проблему - исходное исключение можно теряться из-за возникновения ошибки в секции finally метода StreamReceiverHandler#streamToReceiver. При возникновении ошибки загрузки создается событие FailedEvent, которое обрабатывается в методе FileStorageUploadField.deleteTempFile и там возникает NullPointerException. Эта проблема осложняет анализ, т.к. исходная ошибка не выводится в лог.
Stacktrace:
java.lang.NullPointerException: Cannot invoke "io.jmix.flowui.component.upload.receiver.TemporaryStorageFileData.getFileInfo()" because the return value of "io.jmix.flowui.component.upload.receiver.FileTemporaryStorageBuffer.getFileData()" is null
