Bug? Empty purpose is defined as array

[eliasgruenewald]

    "dataDisclosed": [
        {
            "_id": "454308c8-6860-464b-9881-7e6449bb73ba",
            "category": "Cookies",
            "purposes": [
                {
                    "purpose": [],
                    "description": []
                }
            ],

should rather be

    "dataDisclosed": [
        {
            "_id": "454308c8-6860-464b-9881-7e6449bb73ba",
            "category": "Cookies",
            "purposes": [
                {
                    "purpose":  null,
                    "description": null
                }
            ],

or at least

    "dataDisclosed": [
        {
            "_id": "454308c8-6860-464b-9881-7e6449bb73ba",
            "category": "Cookies",
            "purposes": [
                {
                    "purpose":  "",
                    "description": ""
                }
            ],

Same for legal basis items.
