You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: with_non_recoverable_slow_no_marking_error_spec.rb
    path of file: ./repos/karafka/spec/integrations/pro/consumption/strategies/dlq/lrj_mom
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

# Karafka should be able to recover from non-critical error when using lrj with mom but because
# of no marking, we should move forward, however upon picking up work, we should start from
