下午好，

我设置了一个带有 2 台服务器的 bigchaindb 网络。Ubuntu 18.04 和 BigchainDB 2.2.2。

当我尝试提交 CREATE 操作时，我不断收到“ERR_UNHANDLED_REJECTION”。奇怪的是，这只发生在 nodejs 中，在具有完全相同库的 javascript 中它运行良好。

工作 JavaScript 函数： 

        <script>
            const API_PATH = 'https://block.domain.de/api/v1/'

            const alice = new BigchainDB.Ed25519Keypair()

            const tx = BigchainDB.Transaction.makeCreateTransaction({
                    token: "TestCoin",
                    number_tokens: 1000
                },{datetime: new Date().toString()},
                [BigchainDB.Transaction.makeOutput(BigchainDB.Transaction
                .makeEd25519Condition(alice.publicKey), "1000")],
                alice.publicKey
            )

            const txSigned = BigchainDB.Transaction.signTransaction(tx, alice.privateKey)
            console.log(txSigned);

            let conn = new BigchainDB.Connection(API_PATH)

            conn.postTransactionCommit(txSigned)
                .then(res => {
                    const elem = document.getElementById('lastTransaction')
                    elem.href = API_PATH + 'transactions/' + txSigned.id
                    elem.innerText = txSigned.id
                    console.log('Transaction', txSigned.id, 'accepted')
                })

失败的NodeJS功能：

const bip39 = require('bip39');
const BigchainDB = require('bigchaindb-driver');
  
        var privateKey = req.query.privateKey;
        var publicKey = req.query.publicKey;
        var amount = parseInt(req.query.amount);
        const alice = new BigchainDB.Ed25519Keypair()

        const tx = BigchainDB.Transaction.makeCreateTransaction({
                token: "TestCoun",
                number_tokens: 1000
            },{datetime: new Date().toString()},
            [BigchainDB.Transaction.makeOutput(BigchainDB.Transaction
            .makeEd25519Condition(alice.publicKey), "1000")],
            alice.publicKey
        )
        const txSigned = BigchainDB.Transaction.signTransaction(tx, alice.privateKey)

        let conn = new BigchainDB.Connection(API_PATH)
        conn.postTransactionCommit(txSigned)
        .then(res => {
            res.send("SUCCESS");
        })

我尝试了几乎所有代码片段的划分，但我仍然从 NodeJS 收到以下错误：

node:internal/process/promises:245
          triggerUncaughtException(err, true /* fromPromise */);
          ^
[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "#<Object>".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

我不明白为什么模拟 cpde 在 nodejs 中抛出错误。

谢谢您的帮助！
