与web3进行交易。js有时成功,有时出错

当我们进行任何交易时,每个交易都需要gas,所以我确定了多少gas来进行成功的交易,因为一段时间的交易是成功的,而另一段时间的交易是错误的

“错误:返回的错误:燃气资金不足*价格+价值”

Thanks in advance .


exports.sendTransactions = (sender_account, to_account, p_key, value ) => {
  console.log("sendTRansactions", sender_account,  to_account , p_key , value );
  var admin = sender_account;
  var contract_address = to_account;
  var tx = {
    from: admin,
    to: contract_address,
    gas: 184000,
    data: "",
    value: value
  };
   return web3.eth.accounts.signTransaction(tx, p_key).then((hash) => {
     return web3.eth.sendSignedTransaction(hash.rawTransaction).then((receipt) => {
       return receipt
    }, (error) => {
      return error
      console.log(error);
      // reject(500);
    })
  }, (error) => {
    return error
    // reject(500);
  });
}
