          if dependency_change.updated_dependencies.any?
            Dependabot.logger.info("Creating a pull request for '#{group.name}'")
            begin
              service.create_pull_request(dependency_change, dependency_snapshot.base_commit_sha)
            rescue StandardError => e
              error_handler.handle_job_error(error: e, dependency_group: group)
            end
