I have a registred repository at ssh://git@github.com/flashodoo/free-addons.git#12.0 and run perfectly.

but i have problems when i try to register the 13.0 branch with:

ssh://git@github.com/flashodoo/free-addons.git#13.0

returncode: 128

output:

b"fatal: ambiguous argument 'origin/13.0': unknown revision or path not in the working tree.\nUse '--' to separate paths from revisions, like this:\n'git <command> [<revision>...] -- [<file>...]'\n"

TIA
