The getter 'bytes' was called on null.

I am unable to open a keepass database on Android 9, AuthPass version 1.3.0+115. I have used KeePassXC on Linux to save the database. I have also used NextCloud Keeweb to export the database. They both export them in Keepass 2 format. I am getting the same error that was mentioned below

...I get this error when I try to decrypt the database:

"Unknown error while trying to open file. NoSuchMethodError: The getter 'bytes' was called on null.
Receiver: null
Tried calling: bytes"

This very much sounds like you are saving in kdbx 4 format. In KeepassXC you can select Database -> Database settings ... Security ... Encryption Settings ... and use kdbx 3.1 instead of kdbx 4.

Please verify that it is saving in kdbx 3.1 format. AuthPass does not (yet) support kdbx 4.x (because there is no dart implementation for argon 2 and dart:ffi support (native C interop) is still in a very early phase for dart/flutter)

@roymckenzie have you tried with kdbx 3.1? In the latest version i have also improved the error message so you should see if you are using an unsupported kdbx file version>

Thank you!

fyi authpass now supports kdbx 4.x so this problem should be resolved in the latest version (1.5.2)
