Context: Path: /geographicLocation, Method: POST, Parameter: geographicLocation

Question: Parameter 'in' field must be one of ['query', 'header', 'path', 'cookie']. why it is not considering the "body" inside "in" parameter ?

{"description":"The OSSGeographicLocation or OSSPhysicalStructure to be created","in":"body","name":"geographicLocation","required":true,"schema":{"$ref":"#/definitions/OSSGeographicLocation_Create"}}

"in" syntax is from version 2.x not 3.x
