Hello,

I am seeing an error with a PATCH call I am making and receiving the following error message:  
{"message":"validation failure","errors":[{"dataPath":"","message":"Invalid type: object (expected array)"}]}

However the req.body that I am sending is:  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/2/4/247c12bfd1815325ebe52fe052295d1a0cbecb69.png)  
(Json only version)

```auto
[
    {
        "op": "replace",
        "path": "/label",
        "value": "North America"
    }
]

```

I have opened up a ticket with the external api service for assistance, but I am wondering if I am potentially missing something as I am structuring my JSON body.

Appreciate any help!  
-Will
