This happens because you are passing a Uri instead of the file path. I know on Android 10> we can no longer access the file path where we could previously access the path from the _data column using ContentResolver. I hope the author will provide an option to pass a FileInputStream instead of a file path since there is currently no way to pass a file path unless you copy the file to your applications directory.
