Issue Description: I encountered an issue while using the DataExport plugin in Matomo. When attempting to export data, I received the following error message: "The following error just broke Matomo (v5.0.3): array_diff(): Argument #1 ($array) must be of type array, bool given in /www/wwwroot/10.0.200.91/plugins/DataExport/Services/FileService.php line 219"

Issue Resolved - Missing Directory Caused the Error

Solution: After further investigation, I found that the issue was caused by the absence of the "matomo/tmp/de_backups" directory in my Matomo project. I have resolved the problem by creating the necessary directory.

Thank you for your excellent project!

问题已解决-缺少目录导致错误

解决方案： 经过进一步调查，我发现问题是由于我的Matomo项目中缺少“matomo/tmp/de_backups”目录所致。我通过创建必要的目录解决了这个问题。

感谢您的优秀项目！
