With 2.0, in my callback plugin, I could access the task\_vars like:

`def v2_playbook_on_task_start(self, task, is_conditional): task_vars = task.get_vars() feature = task_vars.get('feature',None) if feature is not None: self._display.display(" Feature: {}".format(feature))`

However, in 2.1, task.get\_vars() returns an empty dict. To access the task\_vars, I have to do this:

`def v2_playbook_on_task_start(self, task, is_conditional): _loader = task._loader task_vars = task.get_variable_manager().get_vars(_loader, task=task) feature = task_vars.get('feature', None) if feature is not None: self._display.display(" Feature: {}".format(feature))`

Is this the preferred method of accessing these vars or is there a better way?

Mike,

Thanks for your post, it was a help to me as I’ve been hit by something similar - and so have a couple of others by the looks of things- see the discussion on [https://github.com/ansible/ansible/pull/16779](https://github.com/ansible/ansible/pull/16779)
