Failing test in CI but not locally

[E C]

I have a series of failing tests I believe all for the same-ish reason. please have a look at my example below

I do have more let() methods within the tests page that are failing with the same response.

I have tried 

• config.use_transactional_fixtures = false within my rails-helper.rb
• all of the things on this page https://freelancing-gods.com/thinking-sphinx/v5/testing.html -- maybe I did not do them in the correct order?

let!(:sausage_category) do
    create(:product_category, name: 'Dinner Sausage',
                                                      display_name: 'Dinner Sausage')context 'when category_filter selected', js: true do
      it 'finds products based on category' do
        check "category_filter_#{sausage_category.id}"
        click_button 'Run Filters'
        expect(page).to(have_content('1 product found for: Dinner Sausage'))
      

Failure/Error: data-association=#{upc.gsub(/\s+/, '')}

thank you for any help
