角2+路径在ErrorHandler error.stack中的应用

Question

我试图使用stacktrace.js报告错误，但是堆栈跟踪中的路径引用“ng://FormModule/MyComponent.ngfactory.js”

    TypeError: Cannot read property 'push' of undefined
    at Object.eval [as handleEvent] (ng:///FormModule/MyComponent.ngfactory.js:668:41)
    at handleEvent (http://localhost/dist/form/angular-vendor.bundle.js:12204:138)
    at callWithDebugContext (http://localhost/dist/form/angular-vendor.bundle.js:13665:42)

Stacktrace.js无法定位包文件及其对应的源映射，因为无法加载此路径

XMLHttpRequest cannot load ng:///FormModule/MyComponent.ngfactory.js. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

是否有人使用WebPack、Stacktrace.js并使源映射工作，或者有人知道如何解决此问题？

Answer 1

通过将{offline: true}作为StackTrace.fromError方法的第二个参数，修正了角6项目中的类似问题，如下所示：

StackTrace.fromError(error, {offline: true}).then(...

就像建议的那样这里。
