Getting invalid option: --format Test::Unit automatic runner, causing run to be marked as failed

cucumber

#1

Rails: 3.2.22
Cucumber: 1.3.18

When my tests all pass, CircleCi is still marking them as failed, because Cucumber is finishing with the following statements:
277 scenarios (277 passed)
1836 steps (1836 passed)
14m27.871s
invalid option: --format

    ((bundle exec cucumber "--format CircleCICucumberFormatter::CircleCIJson --out /tmp/circle-junit.KsAqmSb/cucumber/cucumber.cucumber" "")) returned exit code 1

This is my cucumber.yml file

<%
rerun = File.file?('rerun.txt') ? IO.read('rerun.txt') : ""
rerun_opts = rerun.to_s.strip.empty? ? "--format #{ENV['CUCUMBER_FORMAT'] || 'progress'} features" : "--format #{ENV['CUCUMBER_FORMAT'] || 'pretty'} #{rerun}"
std_opts = "--format #{ENV['CUCUMBER_FORMAT'] || 'progress'} --tags ~@wip"
%>
default: <%= std_opts %> features
wip: --tags @wip:3 --wip features
rerun: <%= rerun_opts %> --format rerun --out rerun.txt --strict --tags ~@wip

Any help/advice is greatly appreciated.
