Enum types require at least one value after adding `use GraphQL::Schema::Visibility` to schema

[fabioxgn]

I have an enum that is dynamically generating the values, like this (removed all other:

module Types
  class BaseEnum < GraphQL::Schema::Enum
    enum_value_class(Types::BaseEnumValue)
  end

  class ReportSlugEnum < Types::BaseEnum
    description "Available reports"

    def self.enum_values(_context)
      {
        some_report: Reports::SomeReport,
        ... # more reports here
      }.map { |k, v|
        GraphQL::Schema::EnumValue.new(k.to_s, owner: self, value: v.name)
      }

After upgrading to 2.4.0, when I add use GraphQL::Schema::Visibility to my schema I get this error:

Unexpected exception raised: GraphQL::Schema::Enum::MissingValuesError
Enum types require at least one value, but ReportSlugEnum didn't provide any for this query. Make sure at least one value is defined and visible for this query.

Hey, sorry for the trouble and thanks for this report. The problem is that Visibility isn't calling def enum_values (but it should!), instead it's calling all_enum_value_definitions (which is only populated via enum_value(...) configs):

https://github.com/rmosolgo/graphql-ruby/blob/dcaaed1cea47394fad61fceadf291ff3cb5f2932/lib/graphql/schema/visibility/profile.rb#L126

I'll update it to work with an example like yours and follow up back here!

Thanks @rmosolgo!
