      $reportTemplateCode: String!
      $after: String
     ) {
        getReportStat(
          input: {crawlId: $crawlId, reportTemplateCode: $reportTemplateCode}
        ) {
          crawlSiteSpeedAuditItems(after: $after, reportType: Basic) {
            nodes {
              opportunityDigest
              element
