REST API Error 'CustomerID' cannot be empty

Hello Everyone,

I'm having a recurring issue I've been facing while using the Acumatica REST API. I am attempting to delete a payment detail from a sales order, and intermittently, I receive the following error message: "'CustomerID' cannot be empty."

The sales order already exists in the system so I shouldn’t need to provide the CustomerID but even if I do I still get the error.

On top of this the error response from Acumatica contains the CustomerID populated as it should be.

Here's a general structure of my API request for reference :

{
  "OrderNbr": {
    "value": "000082"
  },
  "OrderType": {
    "value": "SO"
  },
  "Payments": [
    {
      "id": "544535ce-2f8f-ee11-991e-90ccdfb7d7ce",
      "delete": true
    }
  ]
}

As well as a portion of the response

{
  "id": "e6f8ec91-2b8f-ee11-991e-90ccdfb7d7ce",
  "rowNumber": 1,
  "note": {
    "value": ""
  },
  "error": "'CustomerID' cannot be empty.; CustomerID: 'CustomerID' cannot be empty.",
  ...
  "CustomerID": {
    "value": "2842011255"
  },
