Description

Core classes that store schemas:

• CodegenModel
• CodegenProperty
• CodegenParameter
• CodegenResponse

are missing schema.required information which is a list of strings
At first glance it looks like requiredVars may contain this info but that's not true
That only stores properties whose names are in required.
So if a property is an additionalProperty (not defined in properties) then it does not make it into requiredVars
