The error checking uses the construction x == nil and valid_when_nil or x. But that fails when valid_when_nil evaluates to false. Using the simpler construction x or valid_when_nil with care around booleans would make it easier to see what validation is being done.
Simplifying fixes these args that were nil, but should be boolean.
