undefined method `script_name' for nil:NilClass

Hi. When I type RAILS_ENV=test OPENAPI=1 bundle exec rspec [spec file path] the following error happens.

  NoMethodError:
    undefined method `script_name' for nil:NilClass
  # /usr/local/bundle/gems/rspec-openapi-0.3.12/lib/rspec/openapi/record_builder.rb:64:in `find_rails_route'
  # /usr/local/bundle/gems/rspec-openapi-0.3.12/lib/rspec/openapi/record_builder.rb:19:in `build'
  # /usr/local/bundle/gems/rspec-openapi-0.3.12/lib/rspec/openapi/hooks.rb:12:in `block in <top (required)>'

The following is the content of the target test file.

require 'rails_helper'

RSpec.describe V2::Admin::NotificationsController, type: :request do
  describe 'GET /v2/admin/notifications' do
    subject { get v2_admin_notifications_url, params: params }
    let!(:users) { create_list(:user) }
    let(:params) { nil }

    it { is_expected.to be 200 }
  end
end

I found that if I do not use create_list, no error occurs.

gem version: 0.3.12

What is create_list? I don't think it's a part of rspec-openapi. Could you prepare a repository that reproduces your issue?

Although I couldn't test your create_list case, I could figure out a case where the same backtrace happens. I'll release the fix as v0.3.13.
