Cordova plugin error in success callbackId referenceError: option is not defined

Question

我正在尝试修改现有的 TCPSockets 插件以使用 Cordova 5.0。我已在新线程中将其更改为 运行，因此它不会 运行 离开主线程。在我从插件收到 callbackId 之前，这似乎一直有效。它似乎是伪造的，因为该应用程序无法识别它。我在标题中收到错误，然后显示 "Uncaught Reference Error: option is not defined"。有人可以告诉插件有什么问题吗？

这原来是 javascript 代码中的一个错误。 js代码的回调确实成功了。
