I am trying to use the Netsuite SuiteTalk Rest API to create a Vendor Bill but I keep running into the same error "Error while accessing resource: Please enter value(s) for: Branch Location". I checked that I do have the "Branch Locations" permission and have tried several formats for the location tag but I still get the same error. Below is an example of the JSON i am trying to send.

{
  "entity": {
    "id": 3214
  },
  "TranId": "3442242",
  "item": {
    "items": [
      {
        "item": {
          "id": "123"
        },
        "itemType": "InvtPart",
        "description": "Example Item Description",
        "location": {
          "id": "456"
        },
        "quantity": 3,
        "rate": 0.74,
        "line": 1,
        "amount": 2.22
      }
    ]
  }
}

I am able to list the locations using the API. I have also tried using "location": "456" and "location": 456 but those do not work either. Any help would be greatly appreciated this one has me really stuck
