sshd_config resource no method error

[warroyo]

I am seeing the following error when using the sshd_config resource. The below output is from running inspec cli. I also have the output from inspec shell.

SSH Configuration Banner
      Failure/Error: if @content.empty? && file.size > 0

      NoMethodError:
        undefined method `empty?' for nil:NilClass

Shell output:

sshd_config.content
NoMethodError: undefined method `empty?' for nil:NilClass
from /opt/chefdk/embedded/lib/ruby/gems/2.1.0/gems/inspec-0.16.4/lib/resources/ssh_conf.rb:57:in `read_content'

turning on the --sudo option fixed this
