Problem with git merge --no-ff example

From section 4.8. fast forward merging, in the course the following command is given:
git merge --no-ff bugfix/login-form

In the course video this opens the editor to add in the message etc.

From my system, when I enter that I get:

[name] ~/onedrive/desktop/gitcourse/venus (master)
$ git merge --no-ff bugfix/login-form
merge: bugfix/login-form - not something we can merge

Any ideas?

Hi All,

My mistake - the branch name had a spelling mistake in it.

Called the actual name - and it works as expected,
