为什么 `getRecord()` 由于 `_logger` 相关错误而失败？（使用Hedera SDK）

  • 772

.getReceipt()以下代码在调用时会引发错误。请注意，交易本身是成功的。

    const hcsTopicCreateTx = await new TopicCreateTransaction()
        .freezeWith(client)
        .sign(operatorKey);
    const hcsTopicCreateTxResponse = await hcsTopicCreateTx.execute(client);
    const hcsTopicCreateReceipt = await hcsTopicCreateTxResponse.getReceipt();

这是错误：

file:///Users/user/code/hedera/hedera-code-snippets/hcs-topic-permissioned-write/node_modules/@hashgraph/sdk/src/Executable.js:518
                ? client._logger != null
                         ^
TypeError: Cannot read properties of undefined (reading '_logger')
    at TransactionReceiptQuery.execute (file:///Users/user/code/hedera/hedera-code-snippets/hcs-topic-permissioned-write/node_modules/@hashgraph/sdk/src/Executable.js:518:26)
    at TransactionResponse.getReceipt (file:///Users/user/code/hedera/hedera-code-snippets/hcs-topic-permissioned-write/node_modules/@hashgraph/sdk/src/transaction/TransactionResponse.js:81:54)
    at main (file:///Users/user/code/hedera/hedera-code-snippets/hcs-topic-permissioned-write/hcs-write.js:60:66)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

为什么_logger失踪了？

以下是client对象的初始化方式：

const client = Client.forTestnet().setOperator(operatorId, operatorKey);

还尝试手动初始化记录器，client如下所示：

const client = Client.forTestnet().setOperator(operatorId, operatorKey);
client.setLogger(new Logger(LogLevel.Warn));

然而，同样的错误仍然存​​在。如何解决这个问题？

javascript

    发生错误不是因为未设置记录器对象，而是因为未设置客户端对象。请注意，事务请求与请求不同getRecord，因此客户端对象也需要传递到其中。

    以下代码执行.getReceipt(client)（而不是.getReceipt()），并且这不应引发问题中描述的错误。

        const hcsTopicCreateTx = await new TopicCreateTransaction()
        .freezeWith(client)
        .sign(operatorKey);
    const hcsTopicCreateTxResponse = await hcsTopicCreateTx.execute(client);
    const hcsTopicCreateReceipt = await hcsTopicCreateTxResponse.getReceipt(client);
