Ask a question

hi

I cannot get txhash from parse endpoint of you, and I get the following error when I try to deserialize signed transaction using cardano-serialization-lib, i used rosetta to construct and sign the transaction, what might be the problem?

"Deserialization failed in Transaction.body.TransactionBody because: Invalid cbor: not the right type, expected `Map' byte received `Text'."

thanks, dante

example signed transaction that i want to deserialize:

Hello @dev-dantealighieri, Sorry I don't how you build the transaction? You used rosetta to build this transaction? And then signed it?

Are you using the current release or already node 9.0? Could you provide me more details?

hello @dev-dantealighieri

Rosetta actually adds extra envelopes around it's objects. If you decode (https://cbor.me) your payload, you'll see:

["84a40081825820c9076df9cd4b850ce12c32d9e2d401c20d207c954a8d8b7a746ef6f87436e841010181825839018ff5e406f728a1b21f566ca836b661e8d5cc97417ebbc4ef1a0ca6198ff5e406f728a1b21f566ca836b661e8d5cc97417ebbc4ef1a0ca6191a001967e2021a000285a1031affffffffa10081825820a2f32c4c4c3b33940e6995288aeb0b966f2fa75a4561719149666bad5a842cb758401b84e14cd9b9ade72b8c37512be7d8a354189281ec48767c0899bf0802229d95b842437a22467d597b65c90a1435af4d91b17ebb5db0b618136628a4a2fe170af5f6", {"operations": []}]

The above data structure is not a valid Cardano transaction according to the CDDL specs. But if you take the inside of this "84a400....5f6" and CBOR decode this it does return a valid format.

I've confirmed this by running the below code in CSL:

var signed_tx = "84a40081825820c9076df9cd4b850ce12c32d9e2d401c20d207c954a8d8b7a746ef6f87436e841010181825839018ff5e406f728a1b21f566ca836b661e8d5cc97417ebbc4ef1a0ca6198ff5e406f728a1b21f566ca836b661e8d5cc97417ebbc4ef1a0ca6191a001967e2021a000285a1031affffffffa10081825820a2f32c4c4c3b33940e6995288aeb0b966f2fa75a4561719149666bad5a842cb758401b84e14cd9b9ade72b8c37512be7d8a354189281ec48767c0899bf0802229d95b842437a22467d597b65c90a1435af4d91b17ebb5db0b618136628a4a2fe170af5f6"

var tx = CardanoWasm.wasm.Transaction.from_bytes(buffer.Buffer.from(signed_tx, 'hex'))

console.log(tx.body().outputs().get(0).address().to_bech32())

I hope this clarifies your issue!
