fixes #329

[navaneethaKolichelma]

@HugoMario We have tried with swagger-codegen-cli-3.0.7 but still facing Null pointer exception for content type in query.
Could you please help?

{
"name": "slice-info-request-for-registration",
"in": "query",
"description": "Requested network slice information during Registration procedure",
"content": {
"application/json": {
"schema": {
"$ref": "#/components/schemas/SliceInfoForRegistration"
}
}
}
},

hey @navaneethaKolichelma can you please let me know what generator language (java, spring, kotling, php, etc) are you using? also if you can share the spec document would help too.
