时间锁合同中调用"executeTransaction“函数的问题

Question

事务已经排队，但现在无法执行。

为了使用空字符串作为签名参数的值，我在调用queueTransaction时使用queueTransaction作为参数，调用executeTransaction时使用""作为参数。调用executeTransaction失败，错误是："Timelock::executeTransaction: Transaction尚未排队“。

这是时间锁合同代码的一部分。

  function queueTransaction(address target, uint value, string memory signature, bytes memory data, uint eta) public returns (bytes32) {
    require(msg.sender == admin, "Timelock::queueTransaction: Call must come from admin.");
    require(eta >= getBlockTimestamp().add(delay), "Timelock::queueTransaction: Estimated execution block must satisfy delay.");

    bytes32 txHash = keccak256(abi.encode(target, value, signature, data, eta));
    queuedTransactions[txHash] = true;

    emit QueueTransaction(txHash, target, value, signature, data, eta);
    return txHash;
  }

  function executeTransaction(address target, uint value, string memory signature, bytes memory data, uint eta) public payable returns (bytes memory) {
    require(msg.sender == admin, "Timelock::executeTransaction: Call must come from admin.");

    bytes32 txHash = keccak256(abi.encode(target, value, signature, data, eta));
    require(queuedTransactions[txHash], "Timelock::executeTransaction: Transaction hasn't been queued.");
    require(getBlockTimestamp() >= eta, "Timelock::executeTransaction: Transaction hasn't surpassed time lock.");
    require(getBlockTimestamp() <= eta.add(GRACE_PERIOD), "Timelock::executeTransaction: Transaction is stale.");

    queuedTransactions[txHash] = false;

    bytes memory callData;

    if (bytes(signature).length == 0) {
      callData = data;
    } else {
      callData = abi.encodePacked(bytes4(keccak256(bytes(signature))), data);
    }

    // solium-disable-next-line security/no-call-value
    (bool success, bytes memory returnData) = target.call.value(value)(callData);
    require(success, "Timelock::executeTransaction: Transaction execution reverted.");

    emit ExecuteTransaction(txHash, target, value, signature, data, eta);

    return returnData;
  }

我也有同样的问题，但是我通过设置非空值作为它的签名参数来解决它。
