Invalid value passed for salesorder_id

Invalid value passed for salesorder_id

Hi,
I am using sales return API, details are given below:

API:
https://inventory.zoho.com/api/v1/salesreturns?organization_id=700571811

Post Json Data:

{
"salesreturn_number": "",
"date": "2020-11-12",
"reason": "Testing from API",
"line_items": [
{
"item_id": 2083011000002873023,
"salesorder_item_id": 2083011000004669001,
"quantity": 1,
"non_receive_quantity": 1,
"warehouse_id": 2083011000003214017
}
]
}

When I hit this API I got an error:
{
"code": 4,
"message": "Invalid value passed for salesorder_id"
}

I checked sales order id, i found all details in post form is correct.
why i am getting this error.
Please help me out.

Thanks in advance.
