When updating the Nocobase template version, all files are deleted from the /app/nocobase/storage/up

Hello, actually, the problem is in the title of the topic. I have the Nocobase platform template installed. I periodically update it via the Docker image in EasyPanel. Updates are performed without any problems. But after a while (I can't figure out the pattern), all files (specifically images) that are uploaded via the Nocobase platform web interface simply disappear. They are stored at /app/nocobase/storage/uploads.

At the same time, if I install the Nocobase version directly on the server (also via Docker, but not using Easypanel), all files are saved and are not deleted when the platform version is updated.

Please tell me what the problem might be, where and what I should look at. I am not a programmer and do not know how to code, so I would appreciate detailed instructions on what and where to look to find the real cause.

Maybe something in the Easypanel settings needs to be enabled (or disabled)?
