Error "invalid repository" when pushing

[jjcaballero]

When I do:

$ oras repo ls <registry>/folder/subfolder

I can see the content under folder/subfolder

But if I try to push something on that folder, I get invalid repository:

$ oras push <registry>/folder/subfolder/newFile:v1 localFile.txt
Error: invalid reference: invalid repository

$ cat localFille.txt
this is a dummy file

What can cause this? I have tried different scenarios: when subfolder exists, when subfolder does not exist, giving artifact type, etc.

I understand that an user with write permissions should have permissions to create the subfolder and new file, right?

Any hint will be welcome. Thank you!

repository only allow lower-case letter. newFile is invalid.
