我已成功FungibleCommon在 Hedera Token Service (HTS) 上创建了令牌，并且能够memo毫无问题地设置字段。但是，当我尝试设置令牌的元数据时，memo创建令牌时该字段始终显示为空。

我没有看到任何错误输出，因此这似乎是悄无声息地失败了。

是什么原因造成的？

我使用的是最新的 SDK，终端中没有出现任何错误。我目前正在尝试这样做：

const metadata = {
    "name": "My token name",
    "image": "http://path-to-my-image"
}

async function createFungibleToken() {
    let tokenCreateTx = await new TokenCreateTransaction()
        .setTokenName("Test")
        .setTokenSymbol("TEST")
        .setMetadata(metadata) // <--- HERE
        .setTokenType(TokenType.FungibleCommon)
        .setDecimals(2)
        .setInitialSupply(10000)
        .freezeWith(client);

    let tokenCreateSign = await tokenCreateTx.sign(privKey);
    let tokenCreateSubmit = await tokenCreateSign.execute(client);
    let tokenCreateRx = await tokenCreateSubmit.getReceipt(client);
    let tokenId = tokenCreateRx.tokenId;

    console.log(`Created token with ID: ${tokenId}`);
}

是否有特定的方法来构造元数据？我在这个过程中遗漏了什么？

.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
                         ^

    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？
