QueryFailed

[matisalimbene]

I'm trying to execute a Query using FindTransactionByHash, but I get QueryFailed (code 500) as a response.

I'm on Iroha version: v2.0.0-pre-rc.20 with the following library versions:

    "@iroha2/client": "^7.0.0",
    "@iroha2/crypto-core": "^1.1.1",
    "@iroha2/crypto-target-bundler": "^1.1.1",
    "@iroha2/crypto-target-node": "^1.1.1",
    "@iroha2/crypto-target-web": "^1.1.1",
    "@iroha2/data-model": "^7.0.0",

So for instance, If I use hash value 846F5E5498B4FA615B8137C16CD55707DDE349FE79C7A49B07A838F9A, the code below is how I prepare and execute the query:

const getTXbyHash = async (hash) => {
  logger.info(`[srv] getTXbyHash ... : ${hash}`);

  const { QueryBox, Expression, Value, HashValue } = datamodel;

  // Convert the string to a Buffer
  const buffer = Buffer.from(hash, 'utf8');

  // Create a 32-byte array
  const arrayU8L32 = new Uint8Array(32);

  // Copy the buffer into the 32-byte array
  arrayU8L32.set(buffer.slice(0, 32), 0);

  const query = QueryBox('FindTransactionByHash', {
    hash: Expression(
      'Raw',
      Value('Hash', HashValue('Transaction', arrayU8L32))
    ),
  });

  const { pre, client } = clientFactory();

  try {
    const result = await client.requestWithQueryBox(pre, query);
    const { tag, content } = result;
    if (tag !== 'Ok') return { error: content.enum.tag };

    return {
      data: result,
    };
  } catch (error) {
    logger.error(error);
    return { error: error.message };
  }
};

QueryFailed is the value of content.enum.tag you are returning as an error. However, there is more information about what exactly failed in content.enum.value.

Hey @0x009922, thanks for your help so far!! I do appreciate it.

Just so that is documented, bellow is a sample response for this Query, even tho I'm certain that the Hash I use does exist.

        "tag": "Err",

                        }
                    }
                }
            }
        }
    }
}

I switched logging to DEBUG and saw this:

025-01-15T13:28:06.011852Z DEBUG request{method=POST path=/query version=HTTP/1.1 remote.addr=181.85.41.212:23104}: iroha_core::smartcontracts::isi::query: Executing query=Find transaction with `fc76fa0f0388e0dcb9ecc0cc0bb2f7a07963acb4ec3dea7af6e3ebbf0ee9dcc1` hash

The hash is on lower caps, so would always fail. Unless it is just being shown lowercaps in logging, but it's correct when executing the search. (The hash on the log is from a different test I did, it doesn't correspond to the bytes on the response sample above)

Where you able to use FindTransactionByHash with v2.0.0-pre-rc.20 and SDK 7.0 ?

Iroha is ignorant to the hash case and processes it as a sequence of bytes.

I am now having difficulties with this too. Investigating.
