bool reviver not working

[brandonh-msft]

I have a property of type bool with the following attributes on it already:

    [ArgIgnoreCase]
    [ArgShortcut(ArgShortcutPolicy.NoShortcut)]
    [ArgRequired(IfNot = nameof(Suffix), PromptIfMissing = true)]
    [ArgDescription("Overwrites source files when modified. Defaults to false if unspecified. This or `-suffix` must be given.")]

However when I am prompted to enter a value (because I left it off the arguments), I enter true and am met with an exception:

System.Reflection.TargetException
  HResult=0x80131603
  Message=Object does not match target type.
  Source=System.Private.CoreLib
  StackTrace:
   at System.Reflection.RuntimeMethodInfo.InvokePropertySetter(Object obj, BindingFlags invokeAttr, Binder binder, Object parameter, CultureInfo culture) in System.Reflection\RuntimeMethodInfo.cs:line 342

  This exception was originally thrown at this call stack:

Here is more stack trace detail:
