{
  projects(orderBy: DEPLOYMENT_BOOSTER_SUMMARIES_SUM_TOTAL_AMOUNT_DESC) {
    nodes {
      id
      deploymentBoosterSummaries {
        aggregates {
          sum {
            totalAmount
          }
        }
      }
    }
  }
}

It compare with string rule:

'800' > '7000'

The type of totalAmount is BitInt in schema.
