  # Force resolution of lazy enumerator.
  #
  # The "correct" method to call here would be `#force`,
  # as this method was created to force the eager loading
  # of a lazy enumerator.
  #
  # Unfortunately, JRuby < 9.2.9.0 erroneously eagerly loads
  # the lazy Enumerator during intermediate steps.
  # This forces us to use `#to_a`, as this method works for both
  # lazy and regular Enumerators.
  # Using `#to_a` can mask the fact that we expect a lazy
  # Enumerator.
  responses = responses.to_a
