Sidekiq crash on startup

Commenting out this line in the initializer prevent the error:

SidekiqUniqueJobs::Server.configure(config)

Additional context

Rails 7.1
sidekiq-unique-jobs (master) 8.0.4
Sidekiq 7.2.0

From my understanding:

      def register_reaper_process
        redis { |conn| conn.set(UNIQUE_REAPER, current_timestamp, nx: true, ex: drift_reaper_interval) }
      end

When register_reaper_process is called, RedisClient::CommandBuilder#generate is called and that method is like such:

def generate(args, kwargs = nil)

     # args = ["set", "uniquejobs:reaper", 1699548261, {:nx=>true, :ex=>612}]

        command = args.flat_map do |element|
          case element
          when Hash
            element.flatten # so here  {:nx=>true, :ex=>612} becomes [:nx, true, :ex, 612]
          else
            element
          end
        end
        ...
        command.map! do |element|
          case element
          when String
            element
          when Symbol
            element.name
          when Integer, Float
            element.to_s
          else
            raise TypeError, "Unsupported command argument type: #{element.class}". <---- Exception is raised Unsupported command argument type: TrueClass. It processes, the true from {nx: true, ...} that was flattened
          end
        end
