[Solved] jQuery AJAX Error: Invalid web service call, missing value for parameteron after deploy in IIS

It works fine in local Chrome, IE and Edge if running in Visual Studio but does not work when deployed on local server IIS 10.

The Alert "ERROR!" does come up

{"Message":"Invalid web service call, missing value for parameter: \u0027name\u0027.","StackTrace":" at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
