Kitchen proxy driver sudo dependency

Hi, I am trying to use the proxy driver for kitchen to test an AIX server. I seem to be connecting ok and the converge starts but then I fall foul of a dependency on sudo for some reason and I cant work out how to get around it.

The error is as below
-----> Starting Kitchen (v1.23.2)
-----> Cleaning up any prior instances of
-----> Destroying ...
Finished destroying (0m0.00s).
-----> Testing

my yml looks something like this

    • recipe[mycookbook::test_dummy]
