You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: base_resolver.rb
    path of file: ./repos/gitlabhq/app/graphql/resolvers/issues
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Resolvers
  module Issues
    # rubocop:disable Graphql/ResolverType
    class BaseResolver < Resolvers::BaseResolver
      include SearchArguments

      argument :assignee_id, GraphQL::Types::String,
               required: false,
               description: 'ID of a user assigned to the issues. Wildcard values "NONE" and "ANY" are supported.'
