Hi Ben,

In Local,

In Live,

Invocation of method 'List' in TaggedContent.Widget.Extension.TaggedContentListMethods threw exception NVelocity.Exception.VelocityException : Value cannot be null. Parameter name: g

UnknownException: An error occurred while rendering the 'inBGTaggedMainWrap.vm' script from the 'Tagged Content List' widget (ec913ce1-a28f-4602-af49-8bf572f374e1). (An error occurred while trying to render a widget. Details of the issue were logged for review by the administrator.) ---> NVelocity.Exception.MethodInvocationException: Invocation of method 'List' in  Lenovo.TaggedContent.Widget.Extension.LenovoTaggedContentListMethods threw exception System.ArgumentNullException : Value cannot be null.

It appears you are attempting to parse a guid with a null value within the constructor of your TagServiceCustom class.
