create-script-context tool fails both in Babbage and Alonzo eras

[mkoura]

Summary

create-script-context fails with DeserialiseFailure in Babbage era when using with Alonzo-era transactions:

create-script-context --generate-tx test_minting_context_equivalance_ci0_qml_dummy_tx.signed --out-file test_minting_context_equivalance_ci0_qml_script_context.redeemer --cardano-mode --testnet-magic 42

create-script-context: DecoderFailure (LocalStateQuery HardForkBlock (': * ByronBlock (': * (ShelleyBlock (ShelleyEra StandardCrypto)) (': * (ShelleyBlock (ShelleyMAEra 'Allegra StandardCrypto)) (': * (ShelleyBlock (ShelleyMAEra 'Mary StandardCrypto)) (': * (ShelleyBlock (AlonzoEra StandardCrypto)) ('[] *)))))) Query (BlockQuery (HardForkBlock (': * ByronBlock (': * (ShelleyBlock (ShelleyEra StandardCrypto)) (': * (ShelleyBlock (ShelleyMAEra 'Allegra StandardCrypto)) (': * (ShelleyBlock (ShelleyMAEra 'Mary StandardCrypto)) (': * (ShelleyBlock (AlonzoEra StandardCrypto)) ('[] *))))))))) ServerAgency TokQuerying BlockQuery (QueryIfCurrent (QS (QS (QS (QS (QZ GetCurrentPParams))))))) (DeserialiseFailure 14 "decodeNS: invalid index 5")

create-script-context fails with TextEnvelopeTypeError in Babbage era when using with Babbage-era transactions:

create-script-context --generate-tx test_minting_context_equivalance_ci0_xet_dummy_tx.signed --out-file test_minting_context_equivalance_ci0_xet_script_context.redeemer --cardano-mode --testnet-magic 42

create-script-context: Error creating redeemer from: test_minting_context_equivalance_ci0_xet_dummy_tx.signed Error: ReadTxBodyError (FileError "test_minting_context_equivalance_ci0_xet_dummy_tx.signed" (TextEnvelopeTypeError [TextEnvelopeType "Tx AlonzoEra"] (TextEnvelopeType "Tx BabbageEra")))
CallStack (from HasCallStack):
error, called at app/create-script-context.hs:69:21 in main:Main

Steps to reproduce the behavior

1. generate dummy redeemer file, result looks like

{"fields":[{"list":[]},{"list":[]},{"map":[{"k":{"bytes":""},"v":{"map":[{"k":{"bytes":""},"v":{"int":0}}]}}]},{"fields":[{"fields":[{"fields":[{"int":42}],"constructor":1},{"fields":[],"constructor":1}],"constructor":0},{"fields":[{"fields":[],"constructor":2},{"fields":[],"constructor":1}],"constructor":0}],"constructor":0},{"map":[{"k":{"bytes":""},"v":{"map":[{"k":{"bytes":""},"v":{"int":0}}]}}]},{"list":[]},{"list":[]},{"list":[]},{"fields":[],"constructor":1}],"constructor":0}

2. use the dummy redeemer to generate a dummy Tx
3. derive the correct redeemer from the dummy Tx - while running the corresponding create-script-context command, it fails with DeserialiseFailure or TextEnvelopeTypeError

Actual Result

create-script-context fails in Babbage

Expected Result

The correct redeemer is derived from the dummy Tx.

Actually it doesn't work in Alonzo-era as well:

create-script-context --generate-tx test_minting_context_equivalance_ci0_iom_dummy_tx.signed --out-file test_minting_context_equivalance_ci0_iom_script_context.redeemer --cardano-mode --testnet-magic 42

create-script-context: DecoderFailure (LocalStateQuery HardForkBlock (': * ByronBlock (': * (ShelleyBlock (ShelleyEra StandardCrypto)) (': * (ShelleyBlock (ShelleyMAEra 'Allegra StandardCrypto)) (': * (ShelleyBlock (ShelleyMAEra 'Mary StandardCrypto)) (': * (ShelleyBlock (AlonzoEra StandardCrypto)) ('[] *)))))) Query (BlockQuery (HardForkBlock (': * ByronBlock (': * (ShelleyBlock (ShelleyEra StandardCrypto)) (': * (ShelleyBlock (ShelleyMAEra 'Allegra StandardCrypto)) (': * (ShelleyBlock (ShelleyMAEra 'Mary StandardCrypto)) (': * (ShelleyBlock (AlonzoEra StandardCrypto)) ('[] *))))))))) ServerAgency TokQuerying BlockQuery (QueryIfCurrent (QS (QS (QS (QS (QZ GetUTxOWhole))))))) (DeserialiseFailure 3 "expected map len")\n

The Tx file used with the command -
test_minting_context_equivalance_ci0_iom_dummy_tx.signed.gz

@mkoura I can't reproduce your error. However, now that Testnet is in Babbage era I am getting a different error: DeserialiseFailure 181653839 "Decoding TxIx: too many bytes."

@Jimbo4350 It might be a good idea to ensure this is working before merging your jordan/v2-script-context-test branch.
