hello it does not work. I received following answer from postman. Please help

“You called the function ‘formUrlEncoded’ with these arguments: 
 1: Null (null as Null {encoding: “UTF-8”, mediaType: “application/json; charset=UTF-8″…)

But it expects arguments of these types:
 1: Object

9| formUrlEncoded(vars[‘send-message-request-data’])
 at formUrlEncoded (line: 9, column: 1)
 at main (line: 9, column: 1)” evaluating expression: “output application/x-www-form-urlencoded
fun formUrlEncoded(obj: Object) = obj mapObject {
($$) : $ match {
case x is Object -> write(x, “application/json”)
case x is Array -> write(x, “application/json”)
else -> $
