Fatal:'branch' does not exist and required. 

Throwing this error when i am trying to publish my branch  using git flow bugfix publish branchname

But when I check git status I am able to see my bugfix branch, commit files are available in this branch. 

When I am trying to publish I am getting the above fatal error.
