Description

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')
Rugged::InvalidError: the requested type does not match the type in ODB
from /home/appuser/.bundle/gems/rugged-0.26.0/lib/rugged/repository.rb:190:in `create'

Research direction

Start with the branches.create and repo.create_branch calls shown in the report, then inspect rugged-0.26.0/lib/rugged/repository.rb around line 190. Reproduce the error with the tag object and the v0.1.1 name, and compare the behavior with a commit target; done means creating a branch from a tag works or the limitation is documented.
