  @lma-git Have you considered this?

            if component_usage.save
              ServiceResponse.success(message: 'Usage recorded')
            else
              errors = component_usage.errors
  
              if errors.size == 1 && errors.first.type == :taken # Only unique validation failed
                ServiceResponse.success(message: 'Usage already recorded for today')
              else
                ServiceResponse.error(message: errors.full_messages.join(', '))
              end
            end

Proposal

Minor code refactoring to reduce a line of code
