Issue with vRA 7.3 while creating a request (submitting a request template) through REST API

Hi All,

We've XaaS blueprint with Map field and by default few values are added into the field.

We can see the same default values in request template like below

 "Map": {            "componentTypeId": null,            "componentId": null,            "classId": "Map",            "typeFilter": null,            "data": {                "Disk": "C",                "Memoru": "100"            }        }

But when we post the same template back to vRA, we are getting below error for Map field

{    "errors": [        {            "code": 10101,            "source": null,            "message": "Invalid argument.",            "systemMessage": "Field Map has a NULL schema (ComplexDataType[componentTypeId=null, componentId=null, classId=Map, typeFilter=null, label=null, schema=null])",            "moreInfoUrl": null        }    ]
}

Any idea, What I am missing here ?
