ServiceStack version 5.0.2
I wondered if anyone could give me a pointer to a possible cause of the error shown in the stack trace below. (I am a junior developer, so I am very new to all this.)
We have an ASP.net MVC application which has some ServiceStack.Mvc integration in it. (I suspect we are using ServiceStack's auth provider functionality to handle authentication on MVC controller action requests).
Today we witnessed errors appearing when trying to login to our Web Application. Below is the stack trace of one of the errors that appeared.
The Index action on "MyController" has an 'Authenticate' attribute on it.
[Authenticate]
public class MyController : ServiceStackController<AuthUserSession>
All I can deduct from the stack trace is that after the MVC controller action is invoked, the service stack ServiceRunner tries to execute a service (I have no idea which one) and there is somekind of null reference within the execute method which is throwing an exception.
I wondered if Myths or anyone else had ever seen this before, or could shed any light whatsoever on what service the service runner may have been trying to execute or any information on a possible cause.
The issue disappeared after the web server was rebooted
Exception type: NullReferenceException
Exception message: Object reference not set to an instance of an object.
