Web3py send_raw_transaction ValueError：{'message'：'无效余数'，'code'：-32000}

Question

我正在尝试开始使用以太坊平台和 web3py。 我想调用智能合约，建立交易，签署并发送它。

坚固性代码：

pragma solidity ^0.5.0;

contract UselessWorker {

    int public successfullyExecutedIterations = 0;
    bytes32 public hash = '';
    
    function doWork(int _iterations) public {
        successfullyExecutedIterations = _iterations;
        for (int i = 0; i < _iterations; i++)
        {
            hash = keccak256("ABC");
        }
    }

}

还有我的 python 代码：

from web3 import Web3

web3 = Web3(Web3.HTTPProvider('http://127.0.0.1:7545'))

abi = json.loads('''...''')
contract_address = '0xF0af88Da01E12D49d12300487DDa6E9C6b809AA2'

user_address = '0x348C8455A4C87849A6cd5D1E1bF397291378b51C'
private_key = 'bbd61e7e879cfa63bbdd1202bcc8ff25e4a54a08db3848ebffcc36ffbee6cd45'

contract = web3.eth.contract(address=web3.toChecksumAddress(contract_address), abi=abi)
transaction = contract.functions.doWork(555).buildTransaction({
    'gas': 200000,
    'maxFeePerGas': web3.toWei('100', 'gwei'),
    'maxPriorityFeePerGas': web3.toWei('50', 'gwei'),
    'nonce': web3.eth.get_transaction_count(user_address),
    'from': user_address,
})

signed_txn = web3.eth.account.sign_transaction(transaction, private_key=private_key)
web3.eth.send_raw_transaction(signed_txn.rawTransaction)

每次我尝试运行此代码时，我都会遇到异常。 我怎样才能解决这个问题？

我认为您因为 ganache-cli 而遇到了这个问题

npm uninstall ganache-cli --global
npm install ganache@beta --global
