undefined method `results_in_batches'

If one defines the page_size of a result set smaller than 5 of gets the following error message:
NoMethodError: undefined method `results_in_batches' for false:FalseClass

Example:

search = NetSuite::Records::Location.search({
  preferences: {
    page_size: 14,       # <---------- you get the error if you put a number <5 here
  }
})
search.results_in_batches do |batch|
  @ids = batch.map(&:internal_id)
  ap @ids ;
end

Sometimes I get the same error also on page_sizes that are larger than the result set would be.
For example if I set the page_size to 50 but the result set only contains 20 entries. But the error does not show up every time. Only for number smaller 5 it fails every time.
