win_find: What am I doing wrong here? I'm following the exact syntax from ansible document

ERROR! ‘paths’ is not a valid attribute for a Task

The error appears to have been in ‘/home/vagrant/ansible/win-find.yml’: line 6, column 5, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

- win_find:
^ here

[vm1 ansible]$ ansible --version

config file = /etc/ansible/ansible.cfg

Incorrect indentation, add two spaces to paths and patterns.
