firebase how to download image and update it again?

Question

my image is stored inside firebase storage and its url is stored inside the realtime database. Firebase realtime and storage are both like this:

Type1
----Time1
--------elements of type1
----Time2
--------elements of type2
Type2
....

I let the users change element's time so I have to move an element from a branch to another. My strategy is to create a new element on the new branch and then remove the old one. The problem is in the creation of the new element in the chosen branch, specifically I have problems setting the image of the new element equal to that of the old one. I tried to use Uri.parse() passing the url saved as string in the realtime database and I also tried to use storagereference.getdownloadurl, both I got this error:

    could not locate file for uploading:https://firebasestorage.googleapis.com/v0/b/re...
E/StorageException: StorageException has occurred.
    An unknown error occurred, please check the HTTP result code and inner exception for server response.
     Code: -13000 HttpResult: 0

And it's not sense because If I click that link in the error, it shows me the correct image, so why it can't locate it?! How can I do it?

storageReference = FirebaseStorage.getInstance().getReference().child("images/Anime/General/Test1");
    storageReference.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
        @Override
        public void onSuccess(Uri uri) {
            storageReference = FirebaseStorage.getInstance().getReference().child("images/Anime/Future/Test1");
            storageReference.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    ...
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {

                }
            });
        }
    });

The error is on this line:

storageReference.putFile(uri)...

You have to download the bytes from firebase like this:

storageReference = FirebaseStorage.getInstance().getReference().child("images/Anime/General/Test1");
storageReference.getBytes(1024*1024).addOnSuccessListener(new OnSuccessListener<byte[]>() {
    @Override
    public void onSuccess(byte[] bytes) {
       //here add new element in the server with storageReference.putbytes(bytes)..
    }
});
