Hello,

When I clone the repo, change directory into it, and npm install && npm start I get the following error. It does not seem to work as is, do I need to update any files?

Hi, I have policy id that can mint from multiple admins. can you give a way around we can sign mint NFT transaction from admin and user account simultaneously from react side.

The start script fails with the following error trace of node's GC.

I was only able to run it via react-scripts --max_old_space_size=8186 start.

Is this something to be mentioned in a troubleshooting section? I find this repo so useful for newcomers like me.

HI, I get this issue frequently when i send ADA to some address. Uncaught (in promise) Not enough ADA leftover to include non-ADA assets in a change address

Redeeming from script address wasn't working with previous cost model values, causing a PPViewHashesDontMatch error. As per plutus vasil cost models: https://cardanoupdates.com/commits/c06e3573f9f3bb26a27dfe2340defc46fa4a90a4

When deserializing multiple UTXOs from the same wallet, in some point of the rawUtxos the process crash with this error. When doing the same process to deserialize the same UTXO but not on a loop, it works fine. Anyone maybe knows what could it be?

This is the typescript code that we use to deserialize, and the error is on the picture above

getUtxos= async () => {
    let Utxos = [];
    try {
        const rawUtxos = await this.API.getUtxos();
        for (const rawUtxo of rawUtxos) {
            const utxo = TransactionUnspentOutput.from_bytes(Buffer.from(rawUtxo, "hex"));
            const input = utxo.input();
            const txid = Buffer.from(input.transaction_id().to_bytes(), "utf8").toString("hex");
            const txindx = input.index();
            const output = utxo.output();
            const amount = output.amount().coin().to_str(); // ADA amount in lovelace
            const multiasset = output.amount().multiasset();
            let multiAssetStr = "";


            if (multiasset) {
                const keys = multiasset.keys() // policy Ids of thee multiasset
                const N = keys.len();
                // console.log(`${N} Multiassets in the UTXO`)


                for (let i = 0; i < N; i++){
                    const policyId = keys.get(i);
                    const policyIdHex = Buffer.from(policyId.to_bytes(), "utf8").toString("hex");
                    // console.log(`policyId: ${policyIdHex}`)
                    const assets = multiasset.get(policyId) as Assets
                    const assetNames = assets.keys();
                    const K = assetNames.len()
                    // console.log(`${K} Assets in the Multiasset`)

                    for (let j = 0; j < K; j++) {
                        const assetName = assetNames.get(j);
                        const assetNameString = Buffer.from(assetName.name(),"utf8").toString();
                        const assetNameHex = Buffer.from(assetName.name(),"utf8").toString("hex")
                        const multiassetAmt = multiasset.get_asset(policyId, assetName)
                        multiAssetStr += `+ ${multiassetAmt.to_str()} + ${policyIdHex}.${assetNameHex} (${assetNameString})`
                        // console.log(assetNameString)
                        // console.log(`Asset Name: ${assetNameHex}`)
                    }
                }
            }
            const obj = {
                txid: txid,
                txindx: txindx,
                amount: amount,
                str: `${txid} #${txindx} = ${amount}`,
                multiAssetStr: multiAssetStr,
                TransactionUnspentOutput: utxo
            }
            Utxos.push(obj);
            // console.log(`utxo: ${str}`)
        }
        this.state.Utxos = Utxos
        //this.setState({Utxos})
        console.log(Utxos)
    } catch (err) {
        console.log(err)
    }

this transaction occured https://cardanoscan.io/transaction/7b0b2df3eb915acddf3cba3cf47b564fce6e929dbc9e02b5766006d0b0e7051e

wanted to send 3 ada to addr1qyf9u2cfxhlkhyxywc0kf05zzkgcjv8vvdpr0q6qz3437yk2awc00p8qns6lmmxnw3zrresd34vafvj2yasa7xyr7cqsqh3dev Didn't double check, acctidentally signed and i've sent more than 2000 ada and 200+ wmt tokens to a flint wallet i connected earlier, the 3 ada was send where it was supposed to go (more info on transaction link)

How to recreate: I tinkered around with flint and eternl wallets, was using your boilerplate and switching between the wallets, switched to eternl wallet, sent ada...

Hey, Someone please help me to solve this error.
After running NPM the server is startig and I'm getting error like this in both VS code and in my browser.

Hi. in case I pass many input (utxo of buyer, utxo put onsale) How can I get redeemer index to pass in

const redeemer = CardanoWasm.Redeemer.new(
      CardanoWasm.RedeemerTag.new_spend(),
      // CardanoWasm.BigNum.zero(),
      CardanoWasm.BigNum.from_str('0'),
      redeemerData,
      CardanoWasm.ExUnits.new(
        CardanoWasm.BigNum.from_str(BUY_CARDANO_MEM.toString()),
        CardanoWasm.BigNum.from_str(BUY_CARDANO_CPU.toString()),
      ),
    );
