Parity dev 節點無法通過 web3 py 發送交易

我正在通過 docker 使用具有以下設置的奇偶校驗開發節點：

docker run -d -p 8545:8545 parity/parity --config dev --jsonrpc-interface all --jsonrpc-apis all --jsonrpc-cors "*"

當我嘗試檢索餘額或創建使用者帳戶時，它執行良好。但是，當我嘗試發送事務時，會出現 ReadTimeout 異常：

requests.exceptions.ReadTimeout: HTTPConnectionPool(host='localhost', port=8111): Read timed out. (read timeout=10)

我已經測試了相同的web3.py程式碼可以很好地與兩者ganache或geth --dev.

更新： web3.js掛起類似的請求

var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:8545'));
var BN = web3.utils.BN;

web3.eth.getAccounts(async (err, acc) => {
   let startingBalance = web3.utils.toBN(await web3.eth.getBalance(acc[0]))
   console.log(startingBalance.toString());
   let result = await web3.eth.sendTransaction({
       from: acc[0],
       to: acc[1],
       value: 1000000
   })
   console.log(result);
});

在這種情況下，奇偶校驗節點處於掛起狀態，因為基礎賬戶尚未解鎖。
