Ask a question

I get the following error when i submit transaction, i have no idea why is this happening, what might be the reason?

'Error: Command failed: transaction submit Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraBabbage (ApplyTxError [UtxowFailure (AlonzoInBabbageUtxowPredFailure (ShelleyInAlonzoUtxowPredFailure (MissingVKeyWitnessesUTXOW (fromList [KeyHash "663ed2404fd357ded31b370237e37a6950bb7c9132977dbccedee908"])))),UtxowFailure (UtxoFailure (AlonzoInBabbageUtxoPredFailure (ValueNotConservedUTxO (MaryValue (Coin 46631389) (MultiAsset (fromList []))) (MaryValue (Coin 10000000) (MultiAsset (fromList []))))))])'

Hi, it seems that a witness is missing in your transaction. Are you signing them with all needed keys? What Library are you using for building/signing the transaction?

[HeinrichApfelmus]

The error message indicates that the transaction that you have submitted is incomplete:

• There are missing signatures for some inputs (MissingVKeyWitnessesUTXOW).
• Money is not conserved: The total amount of money in the inputs does not match with the total amount of money in the outputs. (ValueNotConservedUTxO)
