Composer rest 服务器在执行事务时抛出错误

Question

我的网络正常，运行，其余服务器运行正常。但是当涉及到执行交易时，我收到了这个错误。你如何解决这个问题？这与我定义的同行数量有关，还是与将参与者绑定到身份有关。我卡住了。

  "error": {
    "statusCode": 500,
    "name": "Error",
    "message": "Error trying invoke business network.

错误消息提供了有关问题的线索。在调用链代码时，您的 TP 失败并出现以下错误 ReferenceError: alert is not defined 看起来您已尝试使用名为警报的功能。这不存在。如果您在带有 Web 浏览器连接器的 playground 中使用它，那么它之所以有效，只是因为所有代码都在浏览器中执行，并且浏览器定义了 alert 全局函数。
