我想用TRC 20通过tronWeb转移USDT。我得到了TXID和一切，但不知何故，我不能触发智能合约。下面是我的代码：

const TronWeb = require('tronweb');

    // Create a TRON instance
    const tronWeb = new TronWeb({
      fullHost: 'https://api.trongrid.io', // Use the TRON full node URL
    });
    
    // Function to send USDT TRC20 tokens
    async function sendUsdt(addressTo, amount, privateKey) {
      try {
        // Convert the amount to SUN
        const amountSun = tronWeb.toSun(amount.toString());
    
        // Get the contract address of USDT TRC20 token
        const usdtContractAddress = 'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t'; // USDT TRC20 contract address
    
        // Get the address associated with the private key
        const ownerAddress = tronWeb.address.fromPrivateKey(privateKey);
    
        // Create the transfer transaction data
        const transferData = await tronWeb.transactionBuilder.triggerSmartContract(
          usdtContractAddress,
          'transfer',
          {
            _to: addressTo,
            _value: amountSun
          },
          [],
          ownerAddress // Set the owner_address parameter
        );
        transferData.transaction.fee = fee;
    
        // Sign the transaction
        const signedTransaction = await tronWeb.trx.sign(
          transferData.transaction,
          privateKey
        );
    
        // Broadcast the transaction
        const receipt = await tronWeb.trx.sendRawTransaction(
          signedTransaction
        );
    
        console.log('Transaction receipt:', receipt);
      } catch (error) {
        console.error('Failed to send USDT:', error);
      }
    }
    
    // Usage: Call the sendUsdt function with the recipient's address, amount, and private key
    const recipientAddress = 'TRECIPENT';
    const amount = 10; // Amount of USDT to send
    const privateKey = 'MY_PRIV_KEY'; // Set your private key here
    const fee = 100000; // Fee value in SUN
    
    sendUsdt(recipientAddress, amount, privateKey,fee);

这是事务的输出：

我应该尽量避免这种情况吗？先谢谢你了！
