Im creating a transaction using this code:

const tx = { txIn: wallet.balance().utxo, txOut: [ { address: wallet.paymentAddr, value: { ...wallet.balance().value, [MARCELOCOIN]: 1 }, } ], minting: [ { action: 'mint', quantity: 100, asset: MARCELOCOIN, script: mintScript }, ], witnessCount: 2, };

when i try to create the Raw arquive with:

let raw = cardanocliJs.transactionBuildRaw(tx);

It gives me the following error:

option --tx-out: unexpected "N" expecting white space or quantity (word64)

Error: Command failed: cardano-cli transaction build-raw --tx-in 5896209b2eb8eb2e3b19e06335e787c9856661087e6796fd5f483f0a30b923cc#0 --tx-in c6b914dfd086ac8e776c91ea615e847d1e7dc6f447a8cca467371de506ab64a7#1 --tx-out "addr_test1qqmjrep08v07cjn4t3852hr54czxw4m2dyv7wynkk3ufl63xjyzlpj9g68r0n0q3sfgc9vtt8z48z7yff3a4lh9kp2fqa0ccru+998825875+NaN undefined+1 43ad91053eb32da8884e1e5c4b67865d5f46f90072110c8e233261b9.MarceloCoin" --invalid-hereafter 38296439 --invalid-before 0 --fee 0 --out-file /home/cnode/minter/minter/tmp/tx_4ue4nzska.raw

So you see that there is a 'undefined' inside tx-out. I don't know whats the problem.. Can you help me?

  • Hello. Cardano cli has changed recently and that had added extra output in the query which maybe not yet been managed to implement by the library developer. Try contacting the developer or raising an issue on Github Commented Sep 26, 2021 at 12:03

The issue which is simple. The command: cardano-cli query utxo --address {address} --mainnet

Has changed it's output format recently. It now returns an extra field at the end of each TX. A well placed .pop() on the correct JS array will fix it. This extra data belongs to the Smart Contract logics.

Unfortunately I do not use this library and am unfamiliar with it so cannot offer any further guidance.


All solved with the actualization of the cardanocli-js to the 4.0.1 version.

The examples are working great!

  • Yes, version 4.0.0 had problems with extra whitespace in some lines. Version 4.0.1 resolved the issue.
