diagnosing transactions

Diagnosing transactions problems and troubleshooting

If you experience any problems while setting up your network, we are here to help. Logs created by the nodes will help us classify any problems and suggest solutions. The log levels used are info, debug, and trace. This section outlines how to diagnose and solve some problems that you may encounter:

Problem: Failed reading: Your input is either malformed or not hex encoded:

--shelley-era \
--tx-in f5296e996940b1c81f781594293d423b4250a454f5832b0740a923f74460d34#1 \
--tx-out $(cat payment2.addr)+100000000 \
--tx-out $(cat payment.addr)+899832033 \
--invalid-hereafter 335000 --fee 167965 \
--out-file tx001.raw

malformed or not hex encoded:
f5296e996940b1c81f781594293d423b4250a454f5832b0740a923f74460d34

Diagnosis: tx-in is not a valid UTXO

Solution: Make sure that you are using a correct UTXO. You can query this with:

 --address $(cat payment.addr) \
 --mainnet

Problem: ExpiredUTxO

> --tx-file tx001.signed \
> --mainnet

Diagnosis: The current slot is outside the validity interval

Solution: Look at pfUTXOttl and pfUTXOcurrentSlot. Current Slot is ahead of UTXOttl.

Build a new transaction with a invalid-hereafter higher than Current Slot. As a rule of thumb, you will need between 300-500 slots to build, sign, and submit the transaction.

Problem: ValueNotConservedUTxO

> --tx-file tx001.signed \
> --mainnet

Diagnosis: Value not Conserved: (Input UTXO ≠ Fee + Amount sent + Change)

Solution: Check that output amount is equal to input amount

Problem: BadInputsUTxO

--tx-file tx001.signed \
--mainnet

Diagnosis: Bad UTXO transaction index

Solution: Verify the UTXO transaction index using:

 --address $(cat payment.addr) \
 --mainnet
