Feedback for “Hello, World!”

hi,

I'm trying to run the hello-world-lock.py and hello-world-unlock.py scripts, the lock one works fine, but the unlock one does not. I encounter this error "PPViewHashesDontMatch". It seems to be a mismatched between protocol parammeters. With cardano-cli I can input the protocol parameters but I'm not sure how to do it with pycardano.

pycardano.exception.TransactionFailedException: Failed to submit transaction. Error code: 400. Error message: {"contents":{"contents":{"contents":{"era":"ShelleyBasedEraConway","error":["ConwayUtxowFailure (PPViewHashesDontMatch (SJust (SafeHash \"d5fbb74589e2f51ef69544ef67078c1d8615edbd6ea725357c34991fc76e040d\")) (SJust (SafeHash \"d1d662ce473be464ecc35d3edfa0595e167f0e10a5d2f0d6403a261f69b76703\")))"],"kind":"ShelleyTxValidationError"},"tag":"TxValidationErrorInCardanoMode"},"tag":"TxCmdTxSubmitValidationError"},"tag":"TxSubmitFail"}
