Some PDF files under 1MB aren't getting synced and no error visible in the activity list

[whimboo]

Expected behaviour

The desktop client should always sync files with the server when they are created on the disk.

Actual behaviour

The client seems to ignore some files which are under 1MB and doesn't sync them. For brief of a second I can see the blue activity indicator in the Finder, which then hides quickly. Also there is no failure / error listed in the activity list nor a notification shown. That means files won't get synced and will be missed. IMHO this is a serious data loss issue.

Steps to reproduce

1. Save the test.pdf to a NextCloud shared folder
2. Observe that the file is not getting synced
3. When enlarging the file with additional content so that it reaches 1MB it will be synced

Client configuration

Client version: 3.4.2
Operating system: MacOS 12.2.1 [Monterey]
OS language: English
Installation path of client: /Applications/Nextcloud.app

Server configuration

Nextcloud version: 23.0.1
Storage backend (external storage): SSD (ext4)

Logs

1. Client logfile: logs.zip (sorry but I had to strip the logs given that privacy related content would be transmitted otherwise)
2. Web server error log: none at this point given that DietPi doesn't enable logs on the RasperryPi
3. Server logfile: nextcloud log (data/nextcloud.log): Same as above.

I actually saw an update notice on the server to version 23.0.2 yesterday. After applying this update the use case that I layed out above seems to work fine now. I did several tries and none of them failed.

Nevertheless I will keep my eyes open for it and will reopen in case it happens again.
