"No valid root folder found (.nomedia?)" in browser when selecting folder for timeline

[JitteryDoodle]

Describe the bug

I've been trying to get both this app and Recognize to work properly. Luckily, memories does scan all of my photos, unlike Recongize which only seems to want to scan my Photos folder. That being said, I'm getting a "No valid root folder found (.nomedia?)" error in my browser's console when I try to select the root folder for my timeline. Because of this, I cannot use memories even on mobile, where I assume I run into the same issue. I have double and triple checked that the root folder does not have .nomedia, and I even went as far as removing all of my .nomedia files, to no avail.

Steps To Reproduce

1. Setup Memories on Nextcloud following the configuration steps
2. Finish a complete scan of my photos
3. Attempt to select root folder by clicking "Click here to start"
4. After selecting, the folder selection panel goes away and nothing happens.
5. Look in the console and see a 500 error with the message "No valid root folder found (.nomedia?)"

Platform

- OS: Ubuntu, Bazzite, Android
- Browser: Firefox Nightly
- Memories Version: 7.4.1
- Nextcloud Version: 30.0.1 (Docker)
- PHP Version: 8.3.13

• Any errors in the Nextcloud server logs?
  No, weirdly enough. No errors are in nginx, php, or docker logs.

Possibly related to #1028, although unlike that issue I don't have errors in my server logs, which is why I'm creating a new issue.

Whatever this issue is, it's probably the same reason Recongize doesn't scan all of my files.
