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) #5 _ProjectPageState._load (package:butterfly/views/main.dart:183)

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

[e3la]

type 'Null' is not a subtype of type 'FileSystemDirectory<Uint8List>' in type cast

#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) #5 _ProjectPageState._load (package:butterfly/views/main.dart:183)

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

[CodeDoctorDE]

Added in 2.4.0-beta.0, can you try it out and give feedback? Don't forget to make a backup

[CodeDoctorDE]

Also added in 2.3.2

Still not working, but I am more sure it is my webdav at fault.

Hi, did you get an error message? I added a few useful messages if an operation fails
