I'm looking for a way to filter this JSON and retrieve only the cost when fid > 10

Working example, the parent prop is an array:

 [
    {
        "id": 1,
        "properties": {
            "parent": [
                {
                    "fid": 10,
                    "cost": 100
                }
            ]
        }
    },
    {
        "id": 2,
        "properties": {
            "parent": [
                {
                    "fid": 20,
                    "cost": 200
                }
            ]
        }
    },
    {
        "id": 32,
        "properties": {
            "parent": [
                {
                    "fid": 30,
                    "cost": 300
                }
            ]
        }
    }
]

JSONPath = $[*].properties.parent[?(@['fid']>10)].cost

result = [
  200,
  300
]

Not working example, the parent prop is now an object:

[
    {
        "id": 1,
        "properties": {
            "parent": {
                "fid": 10,
                "cost": 100
            }
        }
    },
    {
        "id": 2,
        "properties": {
            "parent": {
                "fid": 20,
                "cost": 200
            }
        }
    },
    {
        "id": 32,
        "properties": {
            "parent": {
                "fid": 30,
                "cost": 300
            }
        }
    }
]

JSONPath = $[*].properties.parent[?(@['fid']>10)].cost

The result is No match
