Passing an Array of object results in errors

I have created an API in ASP.NET Core 2.2 framework as per below sample

[HttpPost]
[Authorize]
public IActionResult AddInvoiceRest([FromBody]AddInvoiceRetailRest[] InvoiceDetail)
{
}

here AddInvoiceRetailRest is class object. I want to pass multiple objects as array.

I am doing testing with postman. I have passed this array from raw body as per below sample.

{
  "InvoiceDetail": [
    {
      "InvoiceMst": [
        {
          "InvoiceNo": 0,
          "CustId": 0,
          "SubTotal": 93,
          "TaxAmount": 13
        }
      ]
    }
  ]
}

problem is here in api i received blank array without adding [Frombody] and when i add [FromBody] , Api doesn't call and shows error like below

{
    "InvoiceDetail": [
        "The input was not valid."
    ]
}

definition of class is

public class AddInvoiceRetailRest   
    {
        public AddInvoiceMst[] InvoiceMst { get; set; }
        public AddInvoiceItemDetail[] InvoiceItemDetail { get; set; }
        public AddInvoicePaymentDetail[] InvoicePaymentDetail { get; set; }
        [Optional]
        public AddInvoiceItemLogDetail[] InvoiceItemLog { get; set; }
        [Optional]
        public string BillDetail { get; set; }
        [Optional]
        public PumpCartObject[] InvoicePumpCart { get; set; }
        [Optional]
        public InvoiceFeeOrDeposite[] InvoiceFeeOrDeposite { get; set; }
    }

Here in the question, I just put a sample of the request, not all keys. Can someone please let me know what I'm doing wrong?

The posted data does not match the expectation of the action.

One option is to create a model that matches the expected data

public class InvoiceDetailModel {
    public AddInvoiceRetailRest[] InvoiceDetail { get; set; }
}

And bind to that in the action

[HttpPost]
[Authorize]
public IActionResult AddInvoiceRest([FromBody]InvoiceDetailModel model) {
    if(ModelState.IsValid) {
        AddInvoiceRetailRest[] invoiceDetail = model.InvoiceDetail;

        //...
    }

    return BadRequest(ModelState);
}

Your issue is that you are expecting array in your API but you are passing a single object json and not an array.

Try this:

[
    {
        "InvoiceMst":
        [
            {
                "InvoiceNo": 0,
                "CustId": 0,
                "SubTotal": 93,
                "TaxAmount": 13
            }
        ]
    }
]
