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: play.rb
    path of file: ./repos/gitlabhq/app/graphql/mutations/ci/pipeline_schedule
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Mutations
  module Ci
    module PipelineSchedule
      class Play < Base
        graphql_name 'PipelineSchedulePlay'

        authorize :play_pipeline_schedule

        field :pipelin
    
        def resolve(id:)
          schedule = authorized_find!(id: id)

          job_id = ::Ci::PipelineScheduleService
            .new(schedule.project, current_user)
            .execute(schedule)

          if job_id
            { pipeline_schedule: schedule, errors: [] }
          else
            { pipeline_schedule: nil, errors: ['Unable to schedule a pipeline to run immediately.'] }
          end
