[Bug]: Error when using WebDav on Android

[e3la]

What happened?

A bug happened!

I perhaps didn't set up dav correctly
I can see the file I made on my desktop saved to dav
but when I try to open it
I get

#0 GeneralDirectoryFileSystem.getRootDirectory. (package:lw_file_system/src/api/base/directory.dart:13)

#1 KeyDirectoryFileSystem.getKeys (package:lw_file_system/src/api/base/key.dart:155)

#2 GeneralKeyFileSystem.listFiles (package:lw_file_system/src/api/base/key.dart:34)

#3 Stream.first. (dart:async/stream.dart:1661)

#4 GeneralKeyFileSystem.getDefaultFile (package:lw_file_system/src/api/base/key.dart:7)

Hello, thanks for reporting. Can you edit the issue to fill in the relevant information in the correct spaces? The platform should be wrong.
Also I think you forgot to paste the full logs since i can see the stack trace but not the error message

type 'Null' is not a subtype of type 'FileSystemDirectory<Uint8List>' in type cast #0 GeneralDirectoryFileSystem.getRootDirectory.<anonymous closure> (package:lw_file_system/src/api/base/directory.dart:13) <asynchronous suspension> #1 KeyDirectoryFileSystem.getKeys (package:lw_file_system/src/api/base/key.dart:155) <asynchronous suspension> #2 GeneralKeyFileSystem.listFiles (package:lw_file_system/src/api/base/key.dart:34) <asynchronous suspension> #3 Stream.first.<anonymous closure> (dart:async/stream.dart:1661) <asynchronous suspension> #4 GeneralKeyFileSystem.getDefaultFile (package:lw_file_system/src/api/base/key.dart:7) <asynchronous suspension> #5 _ProjectPageState._load (package:butterfly/views/main.dart:183) <asynchronous suspension> I'm not sure how to find more of the log, this is what popped up on my android app when I tried to access my dav. Alas this is my first attempt to report a bug. Do let me know what to do to better share the wanted information.

Thanks this helps me. Can you give me a step by step how i can reproduce it?

I created a webdav space on my website hosting, but I can't figure out how to make it work for butterfly. I am betting it is my own error of how I set something up. I don't know what sync root directory check box does. I tried to use it both on the desktop and on my phone and the error I shared is the one I get when I click on file names on my phone. I've used open source software for years but I haven't ever sent in a bug and the option popped up, I just went for it, but I don't actually know how to help beyond what I've said. Is there any documentation on how to get the webdav set up? I could try again.

Sorry for the late response. I will add some error messages to help with this error, I sadly can't see why this happens. For me, it looks like the webdav interface doesn't correctly respond to the request of the app
