Unable to add WebDAV source on version 1.9.9

[iacchi]

EDIT: from the comments below it's clear that it's a general regression of version 1.9.9 and not tied to the Debian version specifically. I've edited the title accordingly.

Describe the bug
I'm running AuthPass from the Debian repository (just installed on a new computer) and I'm trying to access a key file on my personal webdav server. I enter all information correctly but when I click ok to load it I receive an error. Log of the error from the console below. The visual error within the app GUI is: Null check operator used on a null value
The mac version I've been using until yesterday works without any issues (although I created the connection a few versions ago). I've also tired to copy/paste the mac config files inside the linux version but I get other errors.

To Reproduce
Steps to reproduce the behavior:

1. Install AuthPass on linux from the Debian repository
2. Add WebDAV storage
3. Enter valid WebDAV credentials
4. See error

Expected behavior
Key files are loaded from the WebDAV source

Actually, I'm getting the same Null check operator used on a null value error on the Android app too.

Seems to be an issue introduced on the more recent versions.
After rolling back to 1.9.7+162 (via F-Droid) on Android it let me authenticate with the WebDAV source with no issues.
In Linux 1.9.7+1940 (via Flatpak) is also able to authenticate with the WebDAV source for me.

Not sure which version or commit introduced the regression but rolling back to 1.9.7 in the meantime may be worth a shot.

[iacchi]

I can confirm that version 1.9.7+1941 taken from the debian repo (so installed via deb file) works. It must indeed be a general regression with version 1.9.9. I've changed the title of the issue accordingly.

Same issue with version 1.9.9 on iphone, using Apache Httpd webdav module on the server. Unfortunately there is no way to install an earlier version on iphone.

[erikvanoosten]

The only change in authpass/lib/cloud_storage/webdav/webdav_provider.dart since the previous version is this commit. Most probably reverting this commit will fix the issue.

same error on ios17

I'm on 1.9.9+1975 version and I can't connect to the WebDAV services.

@Osika91 imho this should be fixed. maybe you can try the latest beta: https://authpass.app/docs/help-us-beta-testing/#installation

[iacchi]

I can confirm that with the build for Debian dated 27 Jan 2024 I can open my WebDAV source again. I'll test on Android asap but I guess it the bug was common to all platforms it makes sense that it's fixed on all of them.

[hpoul]

I guess there hasn't been a release for some platforms for quite some time.. I'll have to fix a few release scripts and try to publish everything 😅

Thanks you for your feedback. I tried the latest beta but the connection to WebDAV doesn't work. So I download the side load version 1.9.9 1992 and here the WebDAV works.
