Demo Endpoint and Postman OpenAPI Import Returning "Error - No Records Found"

Hello,

I have used the demo link as well as imported the openAPI spec into Postman and used my personal key to attempt to retrieve data. Both of these resulted in the following response, despite there being many records found at https://autoauctions.gsa.gov/GSAAutoAuctions/VehicleListing

`{
"Results": [
{
"status": "NOK",
"error": "NO RECORDS FOUND"
}
]
}`
