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: enable_vision_ai_service.rb
    path of file: ./repos/gitlabhq/app/services/cloud_seed/google_cloud
    
    the code of the file until where you have to start completion: # frozen_string_li
    
      def execute
        gcp_project_ids = unique_gcp_project_ids

        if gcp_project_ids.empty?
          error("No GCP projects found. Configure a service account or GCP_PROJECT_ID ci variable.")
        else
          gcp_project_ids.each do |gcp_project_id|
            google_api_client.enable_vision_api(gcp_project_id)
          end

          success({ gcp_project_ids: gcp_project_ids })
        end
