I experience the same with OneDrive Personal and the built-in browser. Synchronization worked until a week ago when suddenly, I got a "Failed to Upload the KeePass Database" message. The database is about 10MB big.
Interestingly, this only happens with one database. Another one (maybe 1MB) still works.

Hi! I am also experiencing this problem and want to add additional information.
I am running KeePass ver - 2.57.1, DataBaseBackup - ver 2.0.8.6 and KeePass.OneDriveSync - ver 2.1.2.2 on 2 Win 10 desktops and 1 Win 11 laptop. I only get this error when using the laptop. Both desktop systems work fine (although of course, they do not receive changes made using the laptop right now).

According to my backup history, on the Win 11 laptop between 12:04 and 14:28 (EST) on 14-Dec-24, the local .kdbx file changed from 87 kb to 17,115 kb. I cannot say the issue started at that time as I just noticed it yesterday (1-Jan-25) but the local .kdbx files on both Win 10 computers remain at 87 kb and they both continue to work. It is possible I added something large to an entry on the Win 11 laptop at that time and I will search to find if such a thing has happened.

Well, that didn't take long. There is a convenient search for large entries in KeePass and it quickly pointed out that I had scanned 2 pictures of my wife's and my passports and attached them to our passport entries. The pic sizes were approximately 4 Mb and after I removed all 4 pictures, I was back to normal operation on the Win 11 laptop.

So, as a test, I added back one 4 Mb .jpg and tried a save. The error returned. To complete the test, I removed the attachment a second time and did a save. THE ERROR DID NOT GO AWAY! A search for large attachments showed my wife's entry to still be 4 Mb despite the attachment being removed. The only way I could finally get her entry back to normal size was to re-add both pictures (not just one) and then remove both pictures. Her entry returned to a small size and synchronization returned to normal operation.

Hope this all helps. I cannot tell if the issue is the size of the entry or the fact that it was a .jpg attachment or some other issue. The very strange behavior regarding deleting of an attachment I would guess to be a KeePass defect, not a KeyPass.OneDriveSync issue.
