Cannot return null for non-nullable field Redeemer.scriptHash

[alecalve]

Summary

This error happened first when querying this transaction with the following GraphQL query:

query Query($txHash: Hash32Hex) {
    transactions(where: {hash: {_eq: $txHash}}) {
        redeemers {
            scriptHash
        }
    }
}

Steps to reproduce the bug

Run the query against a Cardano graphql instance

Actual Result

Could you provide me the transaction hash you were trying to fetch? Because I can't reproduce it with others.

It's this one https://cardanoscan.io/transaction/95f880700a8ad31515aeece30737868b9dcd26ade91e909b25a4d033bfe4840d?tab=summary

@alecalve Sorry for the very late reply. I started to reproduce the error, but still can't manage to get the same error message. When querying your example request I get the following response: { "data": { "transactions": [ { "redeemers": [ { "scriptHash": null } ] } ] } }

In CardanoScan I see that there is a contract, but the data is null as well. So the response I get seems correct (I double checked it on db-sync database level). If the data is wrong it might be a problem for db-sync.

Did you manage to find the issue for your problem?
