When test\_var is defined inside the playbook it gets passed to the role correctly. However when it’s defined in group\_vars/all.yml Ansilbe won’t find it (undefined) and exits with an error:

fatal: [vagrant] =\> failed to combine variables, expected dicts but got a ‘dict’ and a ‘unicode’

The unicode parameter is actually (Undefined,).
