System Administrators might want to control the amount of details returned with error reports from our web handlers. The default output for errors returned by the web handlers is like this:

// 20171008190642
// http://localhost:8820/web/Entities/Customers/21/Ordersxx?OrderStatus=shipped

Providing that much details about a production environment might be considered a security vulnerability.

Step-by-step guide

Below are the steps to reduce the amount of error details returned by out web handlers:

Open the file .restapplicationsettings (first one located by the AppServer's PROPATH)
Insert or edit existing settings for the following three properties: JsonErrorWriteCallStack, JsonErrorWriteInnerException, JsonErrorWriteProperties. The properties should be set to the quoted value "true" or "false"

Setting all three properties to false, will result in a much shorter error message returned to the caller:

{
  "title": "An application error has occurred (Consultingwerk.OERA.RestResource.InvalidRestAddressException)",
  "error": "Consultingwerk.OERA.RestResource.InvalidRestAddressException",
  "message": "Invalid REST Address: /Customers/21/Ordersxx",
  "messageNum": 0
}
