cannot create branch from tags

[logicminds]

How do I checkout a tag or create a branch from a tag.

Getting Rugged::InvalidError: the requested type does not match the type in ODB

name = 'testbranch'
target = "dd6b748224752d89a83eae0d901cdc03d05dadfa"  # points to a tag
branches.create(name, target)

or

repo.create_branch('sdfadsfsad', 'v0.1.1')
