在公共测试网和具有 1 个矿工的私有网络的开发过程中，此错误不断重复。前者是有道理的，因为存在竞争条件 b/w 矿工和提高 gas 价格可能会有所帮助，但为什么它发生在我的私人网络上，交易很少且采矿难度低？

我使用 web3jssend方法发送两种类型的交易：

 /** executes contract method by creating transaction
 * @param {string} from - payer address
 * @param {string} to - payee address
 * @param {int} amount - number of tokens
 * @param {string} type - transaction type
 */
transferTokens(from, to, amount, type) {
    if (type === 'transfer_to_admin' || type === 'transfer_from_user') {
        return this.contract.methods.transferFrom(from, to, amount).send({ from })
            .catch((err) => {
                logger.info(err);
                return Promise.reject(err);
            });
    }
    if (type === 'transfer_from_admin') {
        return this.contract.methods.transfer(to, amount).send({ 'from': this.coinbase })
            .catch((error) => {
                logger.info(error);
                return Promise.reject(error);
            });
    }
}

其中transfer和transferFrom是 ERC20 标准实现的 Solidity 函数。

任何人都知道如何避免/处理这个错误？
