Cucumber high-level step definition - syntax error, unexpected tIDENTIFIER, expecting keyword_end

I've followed Reuse Cucumber steps.

I'm a noob when it comes to Ruby and Cucumber.
I'm using calabash-android 0.9.0 and cucumber 2.4.0

My calabash_steps.rb:

require 'calabash-android/calabash_steps'

Then /^I add the 1st bestsellers product to bag$/ do
    steps %Q {
         # App restarts and Onboarding screen shows again
         Given I see the text "next"
         Then I press the "next" button
    }
end

Full stacktrace:

The problem was the extra space in steps %Q {, changing it to steps %Q{ made the problem go away
I have the habit of abusing space characters for readability in Java and Javascript

require 'calabash-android/calabash_steps'

Then /^I add the 1st bestsellers product to bag$/ do
    steps %Q{
         # App restarts and Onboarding screen shows again
         Given I see the text "next"
         Then I press the "next" button
    }
end
