Hi all,

Running into a situation where I need to remove elements in an array when a certain value is empty. Thought I could use a value remover in my transformer with an JMESPath Expression (result[?id = ``]), but that does not seem to work.

In this case a need to remove an object in an array whenever the id of this object is null or empty.

Input:

```auto
{
    "result" : [
        {
            "id": "001",
            "value": "vaue 001"
        },
        {
            "id": null,
            "value": "vaue 002"
        },
        {
            "id": "003",
            "value": "vaue 003"
        }
    ]
}

```

Expected Result:

```auto
{
    "result" : [
        {
            "id": "001",
            "value": "vaue 001"
        },
        {
            "id": "003",
            "value": "vaue 003"
        }
    ]
}

```

Help would be appreciated!

Hi @daniellefers,

You can achieve that using a node filter like this:

Could you please kindly try it out?
