Can't save an instance containing 0-N multiple input element which is composed of 4-N multiple input sub-element.

Example:
The geoLocationPolygon consists of two sub-elements: Polygon Point and In Polygon Point. The geoLocationPolygon allows for multiple inputs, ranging from 0 to N, while the Polygon Point sub-element also permits multiple inputs, ranging from 4 to N.

When attempting to populate an instance of geoLocationPolygon, a server error is encountered.

{
  "validationReport": {
    "validates": "false",
    "warnings": [],
    "errors": [
      {
        "message": "object has missing required properties (['@context','@id','pointLatitude','pointLongitude'])",
        "location": "/geoLocationPolygon/0/polygonPoint/3",
        "additionalInfo": {
          "schemaFile": "#",
          "schemaPointer": "/properties/geoLocationPolygon/items/properties/polygonPoint/items"
        }
      },
      {
        "message": "object has missing required properties (['@context','@id','pointLatitude','pointLongitude'])",
        "location": "/geoLocationPolygon/0/polygonPoint/0",
        "additionalInfo": {
          "schemaFile": "#",
          "schemaPointer": "/properties/geoLocationPolygon/items/properties/polygonPoint/items"
        }
      },
      {
        "message": "object has missing required properties (['@context','@id','pointLatitude','pointLongitude'])",
        "location": "/geoLocationPolygon/0/polygonPoint/2",
        "additionalInfo": {
          "schemaFile": "#",
          "schemaPointer": "/properties/geoLocationPolygon/items/properties/polygonPoint/items"
        }
      },
      {
        "message": "object has missing required properties (['@context','@id','pointLatitude','pointLongitude'])",
        "location": "/geoLocationPolygon/0/polygonPoint/1",
        "additionalInfo": {
          "schemaFile": "#",
          "schemaPointer": "/properties/geoLocationPolygon/items/properties/polygonPoint/items"
        }
      }
    ]
  }
}

If we checked the JSON-LD of this instance, there is nothing in polygonPoint.

However, by modifying the multiple input range of geoLocationPolygon from 0-N to 1-N, the error is resolved, and instances can now be saved successfully.
