POI is generated for invalid block number and hash

What is the current behavior?
Currently when querying proofOfIndexing in the admin API with incorrect block hash or invalid block number will each return different POIs. Since invalid POIs can be generated this way, would it make sense for graph-node to error out saying that the block number or hash is invalid for the subgraph (and network that the subgraph is indexing)?

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
Example query for a goerli subgraph with combination of POI queries on the same subgraph:

{
  indexingStatuses(subgraphs: ["QmfDSEUwk2Wp1cVEQ8FcJLVJLbPRfLpG75gLTEHkrSEFRC"]) {
    subgraph
    synced
    health
    fatalError {
      handler
      message
    }
    chains {
      network
      ... on EthereumIndexingStatus {
        latestBlock {
          number
          hash
        }
        chainHeadBlock {
          number
          hash
        }
      }
    }
  }

What is the expected behavior?
It would be great if Graph node would validate the block inputs during a proof of indexing query, as it should prevent manual/accidental input errors

Bắt đầu từ truy vấn proofOfIndexing của admin API và so sánh các đầu vào block của nó với các kết quả blockHashFromNumber và indexingStatuses được hiển thị trong báo cáo. Tái hiện các tổ hợp hash và number hợp lệ và không hợp lệ từ ví dụ. Hoàn tất có nghĩa là các đầu vào block không hợp lệ trả về lỗi thay vì tạo ra các POI khác nhau.
