Object type, required property is not being validated

[Rangababu-R]

Version information
0.1.31

Describe the bug
The Object type property is not being validated, instead the default object is being created

To Reproduce
do not initialize the object property and try to validate, the required property will not raise a validation error

Expected behavior
an error needs to be raised for the object type property.

Additional context
As there was no setter method in snappi the validation is creating the new object for the object typed properties.
