javascript - 未捕获（承诺中）错误：需要交易费用付款人

Question

当我尝试使用幻像钱包执行此操作并响应应用程序时出现此错误

  const transferTransaction = new Transaction()
  .add(SystemProgram.transfer({
    fromPubkey: alice.publicKey,
    toPubkey: feePayer.publicKey,
    lamports: lamportsToSend
  }))
  
  const network = "https://api.devnet.solana.com";
const connection = new Connection(network);
const transaction = new Transaction();
transferTransaction.recentBlockhash = (await connection.getRecentBlockhash()).blockhash;

const { signature } = await window.solana.signAndSendTransaction(transferTransaction);
await connection.confirmTransaction(signature);

Answer 1

transferTransaction.feePayer = alice.publicKey
