Error Handler error.stack 中的 Angular 2+ 路径

Question

我正在尝试使用堆栈跟踪.js来报告错误，但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)

堆栈跟踪.js 找不到捆绑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 并使源映射正常工作，或者有人知道如何解决此问题？

Answer 1

通过将{offline: true}作为第二个参数传递给StackTrace.fromError方法，修复了 Angular 6 项目中的类似问题，如下所示：

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

正如这里所建议的。
