I am trying to filter out vales matching a variable using dataweave.

```
result = {
    "drives": [{
        "id": "0AEBByqXZ0xb4Uk9PVA",
        "name": "QA-zz-SFJobs-Contacts"
    }, {
        "id": "0AC_FdkeL63mHUk9PVA",
        "name": "QA"
    }]
}

```

above is my payload.

Am trying below code

```
%dw 2.0
output application/json
---
{ 
    drives: payload.result.drives[0] filter ((item, index) -> item.name == "QA") 
}

```

which gives me error

error:

You called the function 'Value Selector' with these arguments:
1: String ("{"drives":[{"id":"0AEBByqXZ0xb4Uk9PVA","name":"QA-zz-SFJobs-Contact...)
2: Name ("drives")

But it expects one of these combinations:
(Array, Name)
(Array, String)
(Date, Name)
(DateTime, Name)
(LocalDateTime, Name)
(LocalTime, Name)
(Object, Name)
(Object, String)
(Period, Name)
(Time, Name)

5| drives: payload.result.drives[0] filter ((item, index) -> item.name == vars.folderName)
^^^^^^^^^^^^^^^^^^^^^
Trace:

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

{
drives: payload.result.drives[0] filter ((item, index) -> item.name == vars.folderName)
}".

Expected output:

{
"id": "0AC\_FdkeL63mHUk9PVA",
"name": "QA"
}

how can i achieve this?
