我正在关注https://developer.ibm.com/tutorials/ibm-blockchain-platform-vscode-smart-contract/上的教程，当我通过 IBM 区块链平台 VS 代码扩展提交交易时，我收到错误：

“提交交易时出错：未收到成功事件”。

调用的函数是“实例化”，如下所示：

    public async instantiate(ctx: Context): Promise<any> {
        const greeting = { text: 'Instantiate was called!' };
        await ctx.stub.putState('GREETING', Buffer.from(JSON.stringify(greeting)));
    }

即使抛出错误，运行它也会成功写入账本。之后我能够查询分类帐并看到正确的值“{ text: 'Instantiate was called!' }”被退回。

这是我运行单元测试时的错误跟踪instantiate。希望能帮助到你：

local fabric提交交易后，我注意到 VS Code 中的输出存在差异：

[4/13/2019 9:41:22 PM] [INFO] fabricvscodelocalfabric_peer0.org1.example.com|2019-04-12 12:17:55.210 UTC [common.deliver] DeliverBlocks -> WARN 05a 拒绝交付 172.19。 0.1:34608 由于信封验证错误：信封时间戳 2019-04-13 11:41:22.439 +0000 UTC 与当前服务器时间 2019-04-12 12:17:55.210409997 +0000 UTC m=+169.648611001 相差超过 15m0s

这看起来像是某种时间差异，peer0所以我进入它的 bash 并跑去date查看不正确的服务器时间（2019-04-12 12:17:55），然后我开始尝试更正服务器时间。

在此之后，我重新尝试Submit Transaction并且它没有抛出错误！

我试图通过拆除结构然后重新启动来再次复制原始问题，但提交事务现在似乎按预期工作。
