I can build and sign a tx with no errors using:

cardano-cli transaction build --alonzo-era \
--testnet-magic 8 \
--tx-in 20445d5c68e1759f1371a86ecca773b76463fba3831f128fd2f7834de38ae6ec#0  \

cardano-cli transaction sign --tx-body-file txs/eliInit/tx.build --testnet-magic 8 --signing-key-file ./wallet2/payment.skey --out-file txs/eliInit/tx.signed

My 1 input datum and 2 output datums add up to a total of 2888 bytes.

bash-4.4# du -b datums/elidInit/elid.json 
481     datums/elidInit/elid.json
bash-4.4# du -b datums/eliInit/elid.json 
477     datums/eliInit/elid.json
bash-4.4# du -b datums/eliInit/eli.json 
1930    datums/eliInit/eli.json

Yet when I try to submit, I run into the following error:

bash-4.4# cardano-cli transaction submit --testnet-magic 8 --tx-file txs/eliInit/tx.signed
Command failed: transaction submit  Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraAlonzo (ApplyTxError [UtxowFailure (WrappedShelleyEraFailure (UtxoFailure (ExUnitsTooBigUTxO (WrapExUnits {unWrapExUnits = ExUnits' {exUnitsMem' = 30000000, exUnitsSteps' = 10000000000}}) (WrapExUnits {unWrapExUnits = ExUnits' {exUnitsMem' = 40134886, exUnitsSteps' = 14936123959}})))),UtxowFailure (WrappedShelleyEraFailure (UtxoFailure (MaxTxSizeUTxO 19142 16384)))])

How do I get the transaction to not error our when submitting? My scripts conduct some time checks, signing checks, and checks on the output datums.

Apparently there is a problem with the size of your transaction, which is: 19142

But there is a limit, you can find it on the protocol-params file:

maxTxSize: 16384 bytes

Try to modify it, to decrease the size of the transaction.

  • I am pretty sure that the size of the transaction is relatively small from the above numbers. Is there any way to tell where that size is coming from?

  • It's not the max Tx size, but rather the exunits. Try lowering those
