Hello,

So the error is saying the body of the request is coming out empty as per the swagger description

being the sample request body on this format

{
  "Name": "string",
  "Priority": "High",
  "SpecificContent": {},
  "DeferDate": "2022-07-26T17:34:21.803Z",
  "DueDate": "2022-07-26T17:34:21.803Z",
  "RiskSlaDate": "2022-07-26T17:34:21.803Z",
  "Reference": "string",
  "Progress": "string"
}

When analyzing your request body:

$post_data = [
            'itemData' => ['Name' => $queueName, 
        'Priority' => $queueItemInfo['Priority'],
        'DeferDate' =>'2022-09-21T20:22:37.443Z', 
        'DueDate'=> $queueItemInfo['DueDate'], 
        'RiskSlaDate'=>$queueItemInfo['RiskSlaDate'], 
        'Progress'=> $queueItemInfo['Progress'], 
        'Reference'=>$queueItemInfo['Reference'],
        'SpecificContent' => ['Arg1' => $arg1, 'Arg2' => $arg2]]];

I believe is being rendered like this, if that’s the case “itemData” is not defined in the API reference, therefore is saying queueItemDataDto is null

"itemData": {
  "Name": "string",
  "Priority": "High",
  "SpecificContent": {},
  "DeferDate": "2022-07-26T17:34:21.803Z",
  "DueDate": "2022-07-26T17:34:21.803Z",
  "RiskSlaDate": "2022-07-26T17:34:21.803Z",
  "Reference": "string",
  "Progress": "string"
}

not familiar with PHP (my bad if I got the language incorrectly) but have you tried sending your request body like this?

CURLOPT_POSTFIELDS => json_encode($post_data.itemData)

NOTE: my syntax may be incorrect

My recommendation is build your request from the bottom up, using as few attributes as possible and add them as you find a working point, If you haven’t, you may build and test your requests from the swagger UI before translating them into your app code. I left below a few resources.

If you are still experiencing problems, please attach your request body in JSON format and your request headers to further evaluate them.
