Fix typo and ensure params are passed as strings
Fix typo and ensure params are passed as strings

The first fix here is simply to rename 'res' to 'new_resource'. This
was an artifact of some older code that had been here.

The second change is to ensure that all parameters are shelled out as
strings (instead of their native integer, bool, whatever).
