BUG: Unique items in array of dictionaries

[ghandic]

Since current implementation is making use of sets in Python, dicts are not hashable, change would be needed to rectify this.

Example

"errors": {
            "type": "object",
            "properties": {
                "validationErrors": {
                    "type": "array",
                    "minItems": 0,
                    "maxItems": 2,
                    "uniqueItems": false,
                    "items": [
                        {
                            "type": "object",
                            "$state": {
                                "error": "lambda: random.choice([{'code':'3013','message':'Mandatory field is either Null or blank','field':'IDNumber'}, {'code':'2013','message':'Mandatory field is either Null or blank','field':'IDNumber'}])"
                            },
                            "properties": {
                                "code": {
                                    "type": "string",
                                    "description": "Error code from Digital gateway validation checks",
                                    "$provider": "lambda: state['validationErrors[0]']['error']['code']"
                                },
                                "message": {
                                    "type": "string",
                                    "description": "",
                                    "$provider": "lambda: state['validationErrors[0]']['error']['message']"
                                },
                                "field": {
                                    "type": "string",
                                    "description": "",
                                    "$provider": "lambda: state['validationErrors[0]']['error']['field']"
                                }
                            },
                            "required": ["code", "message", "field"]
                        }
                    ]
                }
            },
            "required": ["validationErrors"]
        }
