If you are using Visual Studio for debugging your server code, check the Exception Settings (if they are not visible go to the menu 'Debug' -> 'Windows -> 'Exception Settings' and they should appear in the lower right by default) and make sure that the debugger is set to break on the relevant exceptions - in your case I would check the 'Common Language Runtime Exceptions' tree, specifically the 'ArgumentOutOfRangeException' there (but I usually enable the whole tree).

With this setting enabled on your next debug session, the visual studio debugger should break where the exception is thrown and show you a popup with details.

  • Have try catch for the whole code block.
  • Mark break point on catch.
  • So that you find from where it is throwing the exception.
