Unescaped control character around character 981.Error while parsing JSON

Answer 1

to be sure (as people make fool copy/paste...) , I build my object safe: ..

private final func fillWith(
     id: Int,
     name: String?
) {
    
    self.id = id
    self.productName = name?.replacingOccurrences(of: "\t", with: "")
    self.productName = self.productName?.replacingOccurrences(of: "\n", with: "")

So no prob when sending Up.
