Error doing a POST request Omnis 8.1.3

[An]

Hi All,

After making a huge step thanks to Bruno I've now ran in to a new error.

As content for my post I send this in JSON format. 

[     {         "MerchantOrderNo": 1001598,         "OrderId": 1     } ] 

This is created using following code:
Do OJSON.$listorrowtojson(iList,,errorText) Returns iContentBinary
Do OJSON.$formatjson(iContentBinary) Returns iContentChar
Calculate iContentChar as replaceall(iContentChar,kCr,' ')


This matches with the API reference which say's it should be this
{
  "MerchantOrderNo": "string",
  "OrderId": 0
}

But I get following error message. Can it be that this is also something that changed using the new OW3 Worker Object?
{
    "StatusCode": 400,
    "Success": false,
    "Message": "Some fields did not pass validation, see ValidationErrors for details.",
    "ValidationErrors": {
        "model": [
            "Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'MM.WebApi.App.ViewModels.OrderAcknowledgementViewModel' because the type requires a JSON object (e.g. {\"name\":\"value\"}) to deserialize correctly.\r\nTo fix this error either change the JSON to a JSON object (e.g. {\"name\":\"value\"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.\r\nPath '', line 1, position 1."
        ]
    }
}

Thanks very much for helping a Omnis newbie :)

>> Hi An,
>> 
>> You are using the "old" http client which has a dependency with Java.
>> 
>> With 8.1.3, you should rather user the new OW3 worker object, which doesn't have this flaw.
>> 
>> Have a look at the library at Hub / Samples / HTTP OW3 worker object for a working example of POST request
