Hello dear friends hope everybody is good today ?When following : https://station.jup.ag/docs/apis/swap-api#guide-for-v6-swap-api-code-exampleI can't send my transaction to a jito bundle or normal
- Get a quote like this :
{ inputMint: 'So11111111111111111111111111111111111111112', inAmount: '10000000', outputMint: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v', outAmount: '1953696', otherAmountThreshold: '1953696', swapMode: 'ExactIn', slippageBps: 0, platformFee: null, priceImpactPct: '0', routePlan: [ { swapInfo: [Object], percent: 100 } ], contextSlot: 300046736, timeTaken: 0.010705948}- Custom quote (RoutePlan), outputMint , etc .... :
{ inputMint: 'So11111111111111111111111111111111111111112', inAmount: '10000000', outputMint: 'So11111111111111111111111111111111111111112', outAmount: '10000000', otherAmountThreshold: '9000000', swapMode: 'ExactIn', slippageBps: 0, platformFee: null, priceImpactPct: '0', routePlan: [ { swapInfo: [Object], percent: 100 }, { swapInfo: [Object], percent: 100 } ], contextSlot: 300046736, timeTaken: 0.010705948}- Sending to a Jito URL : https://URL/v1/transactions with
await fetch('https://quote-api.jup.ag/v6/swap', { method: 'POST', headers: {'Content-Type': 'application/json' }, body: JSON.stringify({ quoteResponse : MyQUOTE, userPublicKey: wallet.publicKey.toString(), wrapAndUnwrapSol: false, prioritizationFeeLamports: { jitoTipLamports: 10000, } }) })).json();Don't work and return error :
- TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be of type string or an instance of Buffer, ArrayBuffer, or Array or an Array-like Object. Received undefined from transaction.sign([wallet.payer]);
const swapTransactionBuf = Buffer.from(swapTransaction, 'base64'); var transaction = VersionedTransaction.deserialize(swapTransactionBuf); const wallet = new Wallet(Keypair.fromSecretKey(bs58.decode('5qHsXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXbfDvBf'))); transaction.sign([wallet.payer]);A simple quote before swap work good but not when changing quote fetched
