Generate a schema containing specific field with "additionalProperties": true

[huaqing1994]

Can I generate a schema like

"objectType": {
    "type": "object",
    "properties": {
        "field1": {
            "additionalProperties": true
        },
        "field2": {
            "additionalProperties": true
        }
    }
}
