validation of required input parameters

[gregb502]

In petstore api, the photoUrls property of the Pet definition is a required property.

When I tried to register a new pet using curl, if I set the photoUrls to null, the pet is registered in the store.

curl -X 'POST'
'https://petstore.swagger.io/v2/pet'
-H 'accept: application/json'
-H 'Content-Type: application/json'
-d '{
"id": 123456789987,
"category": {
"id": 0,
"name": "string"
},
"name": "doggie",
"photoUrls": null,
"tags": [
{
"id": 0,
"name": "TheTag"
}
],
"status": "available"
}'

When I tried to look at this pet using the path /pet

curl -X 'GET'
'https://petstore.swagger.io/v2/pet/123456789987'
-H 'accept: application/json'

{"id":123456789987,"category":{"id":0,"name":"string"},"name":"doggie","tags":[{"id":0,"name":"TheTag"}],"status":"available"}

The answer does not contain the required photoUrls property (and some of the sdk generated with the swagger generator that check that this property is set (python) produce an error.)

Thanks
