CLI round-tripped the transaction using the new echo command without errors

cardano-cli conway transaction echo --tx-file ../new.tx --out-file ../copy.tx
...
diff <(cat ../new.tx | jq -r .cborHex) <(cat ../copy.tx | jq -r .cborHex) # shows no differences

Steps to reproduce Steps to reproduce the behavior:

1. Start a local testnet
2. Run the e2e test

Expected behavior The transaction is expected to pass, at least the deserialization phase.

System info (please complete the following information):

• OS Name: [e.g. Ubuntu]
• OS Version [e.g. 20.04]
• Node version v8.9.1
• CLI version

I have no permission to edit the description, so let me add here some more details.

Steps to reproduce the behavior:

1. Start a cardano-js-sdk local testnet
2. Run the cardano-js-sdk e2e test (I'm available to pair with a cardano-node developer to support in this process)

... but I think the details reported by @aniketd could be enough to investigate the issue.

System info:

• OS Name: Ubuntu in WSL2 on Windows 10
• OS Version: Ubuntu 20.04 LTS
• Node version v8.9.1
• CLI version v8.9.1 (even this should be not relevant)

Sorry @aniketd , is there some updates on this issue? I saw the previous comment which warried me.

Thank you

@iccicci thanks for the mention! This has been fixed here https://github.com/IntersectMBO/cardano-ledger/pull/4288 . For a quick summary, the problem was in decoding, not the transaction itself, but the resulting PredicateFailure.
