A minimal example:

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "id": "http://example.com/exampleschema.json",
    "title": "Title",
    "description": "Description",
    "type": "object",
    "properties": {
        "topics": {
            "type": "array",
            "items": {
                "type": "object",
                "properties": {
                    "score": {
                        "type": [
                            "null",
                            "number"
                        ]
                    }
                },
                "required": [
                    "score"
                ]
            }
        },
        "last_read": {"type": "null"},
        "rights": {
            "type": [
                "null",
                "string"
            ]
        },
        "resource_links": {
            "anyOf": [
                {"type": "null"},
                {
                    "type": "object",
                    "properties": {
                        "PropA": {"type": "string"},
                        "PropB": {"type": "string"}
                    }
                }
            ]
        },
        "virtual_pages": {
            "type": [
                "integer",
                "null"
            ]
        },
        "duration_seconds": {"type": "null"}
    },
    "required": [
        "duration_seconds",
        "last_read",
        "resource_links",
        "rights",
        "topics",
        "virtual_pages"
    ]
}

With schema-generator this gives something like:

// Title Description
type Title struct {
  DurationSeconds nil `json:"duration_seconds"` // error here
  LastRead nil `json:"last_read"`                             // error here also
  ResourceLinks interface{} `json:"resource_links"`
  Rights interface{} `json:"rights"`
  Topics []*TopicsItems `json:"topics"`
  VirtualPages interface{} `json:"virtual_pages"`
}

// TopicsItems
type TopicsItems struct {
  Score interface{} `json:"score"`
}

Basically nil can be changed to *string (see this SO question) and interface{} can be changed to *int, *float64, and *string in many of the above cases.

Sorry for the late reply, but do you have a complete example?
