InvalidResponseError：返回错误：方法eth_sendTransaction不存在/不可用

问：

我正在尝试使用 web3 在 BSCtest 上与智能合约进行交互。我认为错误发生在这一行中

rs = await TokenContract.methods.transfer(receiverAddress, 100000).send({
    from: myAddress,
    gas: 3000000
  })

完整代码：

require('dotenv').config();
const {Web3}  = require('web3');

myPrivateKey = process.env.PRIVATE_KEY;
const TokenAddress = "0x026e6631A3514e0B52c3D33c09D52Ab9574C2703";
const TokenAbi = [...]

myAddress = "0xb5253E9D3Ec90b7887Eec27a7F280D176Fd542A3";
receiverAddress = "0xF37ab5FC6D6093E281Be2129e10D5f86e2f20E11";

async function interact(){
  web3 = new Web3("https://data-seed-prebsc-2-s3.binance.org:8545");
  TokenContract = await new web3.eth.Contract(TokenAbi, TokenAddress);
  // myBalance = await TokenContract.methods.balanceOf(myAddress).call();
  // console.log(myBalance);

  await web3.eth.accounts.wallet.add({
    privateKey: myPrivateKey,
    address: myAddress
  });
  receiverBalanceBefore = await TokenContract.methods.balanceOf(receiverAddress).call();
  rs = await TokenContract.methods.transfer(receiverAddress, 100000).send({
    from: myAddress,
    gas: 3000000
  })

  receiverBalanceAfter = await TokenContract.methods.balanceOf(receiverAddress).call();
  console.log(receiverBalanceBefore, receiverBalanceAfter);
}
interact();

我在堆栈溢出时遇到了另一个类似的错误，例如将 0 传递给值参数。

contract.methods.test().send({from:account, value: 0}) 

但它对我不起作用
