在LogPersonDetails中，我一直得到一个错误：
Error ArgumentException：无法将System.String转换为Card.Printer.CardHolder，不确定原因。
它传递的值是这样的：

{"FirstName":"ad","LastName":"asd","Email":"asd","CardNumber":"asd"}

我的理论是，它是这样做了两次，但当检查它，我得到：
$exception {“将值“{“FirstName”：“ad”，“LastName”：“asd”，“Email”：“asd”，“CardNumber”：“asd”}”转换为类型“Kiosk.Card.Printer. CardHolder”时出错。Path ''，line 1，position 86."} Newtonsoft.Json.JsonSerializationException
这是Chromium WebView 2 Control和.NET到JavaScript的互操作。
有什么想法？
