      When using the type `Optional` without any arguments, this could result in an internal error. This is now fixed. Note that `Optional` on its own means the same as `Any` and thus you should always supply a type argument T with is the desired type if the value is not `undef`.

    Description

      A class with an optional parameter with no type that defaults to undef isn't handled well by /opt/puppetlabs/puppet/lib/ruby/vendor_ruby/puppet/pops/types/type_mismatch_describer.rb

      For example if I have a class:

      class test::validation (
      		 
       Optional $whatever = undef
      		 
      ){
      		 
      notice($whatever)
      		 
       
      }

      and in hiera:

      test::validation::whatever: 1234

      Applying the class to an agent results in the stack trace I've attached here.
