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: projects_controller.rb
    path of file: ./repos/gitlabhq/app/controllers/projects/error_tracking
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Projects
  module ErrorTracking
    cl
    
      def index
        service = ::ErrorTracking::ListProjectsService.new(
          project,
          current_user,
          list_projects_params
        )
        result = service.execute

        if result[:status] == :success
          render json: { projects: serialize_projects(result[:projects]) }
        else
          render(
            status: result[:http_status] || :bad_request,
            json: { message: result[:message] }
          )
        end
