Can't upload any attachment

[000exploit]

I have double-checked that everything is working from the web version, but when I try to upload a file for a transaction, I get an 'unknown error' in the client and while uploading the file, I see 0 B instead of its size. Also when uploading any attachments I get the error production.ERROR: Body of attachment is empty. on the server. Turns out it works in emansih/FireflyMobile as well.

Waterfly III 1.0.1 from F-Droid
Firefly v6.1.13
Android 14
LineageOS 21

Hi, could you please turn on the debug logs, try it again, and send it to me (by disabling the log option)? (Alternatively you can also upload to github, just make sure to censor everything, like your host etc). Thank you!

I don't see any explicit error messages here, but there are 2 log files with creating a new transaction with attachment and editing an existing transaction. Of course, they're censored enough.
