Recording a Payment to an Invoice in Wild Apricot

I am trying to create my scenario that records a payment to an invoice using Google Sheets and the Wild Apricot API. I cannot find and fix the error. I get the data error message below. I’ve also added screenshots and my json script. I can’t find the rogue “:”
