I can’t seem to upload individual files to my rclone Koofr drive on Android. I set it up by pasting the rclone config from my PC into the Android app in JSON format. It apparently works, I can do almost everything normally: access the drive, see the files, move items around, delete, download them, and upload images using the "take photo" option. I can also upload folders; when I do, my Android system first prompts me with a message like "Allow S3Drive to access this folder," and after I click "Allow," it works.
However, for individual files, I get a "Null check operator used on a null value" error, and there’s no prompt asking for permission to access the folder. I’m not sure if this is a permissions issue or something missing in the setup. I tested it by uploading a folder called "books." It asked for permission to access the folder, which I granted, and the upload completed successfully. So I figured now that I had permission inside this folder I could upload a single file from inside this folder but it gave the same error.
