So I was using a json path syntax for the json below

{"documents": [
                {
                    "id": 1231,
                    "doctType": "FFS",
                    "docValue": "3123123",
                    "isPrim": 0
                },
                {
                    "id": 1232,
                    "docType": "National Identity Card",
                    "docValue": "0000840317",
                    "isPrim": 1,
                    "resources": [
                        {
                            "id": 23893452,
                            
                            "name": "national card"
                            
                        },
                        {
                            "id": 52524055,
                            
                            "name": "national card front"
                            
                        },
                        {
                            "id": 4266737,
                            
                            "name": "physical Form"
                            
                            
                        }
                    ]
                },
                
                 {
                    "id": 1233,
                    "docType": "National Identity 1234",
                    "docValue": "312312",
                    "isPrim": 1,
                    "resources": [
                        {
                            "id": 23893452,
                            
                            "name": "national card back"
                            
                        },
                        {
                            "id": 52524055,
                            
                            "name": "national card front"
                            
                        },
                        {
                            "id": 4266737,
                            
                            "name": "physicalForm"
                            
                        }
                    ]
                }
                ]}
                
                

Here I use the below mentioned json path

$.documents[?(@.isPrim==1)]

This returns the below output

[ { "id": 1232, "docType": "National Identity Card", "docValue": "0000840317", "isPrim": 1, "resources": [ { "id": 23893452, "name": "national card" }, { "id": 52524055, "name": "national card front" }, { "id": 4266737, "name": "physical Form" } ] }, { "id": 1233, "docType": "National Identity 1234", "docValue": "312312", "isPrim": 1, "resources": [ { "id": 23893452, "name": "national card back" }, { "id": 52524055, "name": "national card front" }, { "id": 4266737, "name": "physicalForm" } ] } ]

Now I want to get the first JSON in this array or the first element, for that I tried using

$.documents[?(@.isPrim==1)][0]

but this doesn’t work. Please help me understand how can I pick the first element here. I can use any other filter for this. My need is to pick the first element.
