ErrorHandler error.stack 中的 Angular 2+ 路径

Question

我正在尝试使用 stacktrace.js 报告错误，但堆栈跟踪中的路径引用了“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)
    at Object.debugHandleEvent [as handleEvent] (http://localhost/dist/form/angular-vendor.bundle.js:13253:12)
    at dispatchEvent (http://localhost/dist/form/angular-vendor.bundle.js:8808:21)
    at http://localhost/dist/form/angular-vendor.bundle.js:9419:20
    at HTMLAnchorElement.<anonymous> (http://localhost/dist/form/angular-vendor.bundle.js:29309:53)
    at ZoneDelegate.invokeTask (http://localhost/dist/form/polyfills.bundle.js:7779:31)
    at Object.onInvokeTask (http://localhost/dist/form/angular-vendor.bundle.js:4090:33)
    at ZoneDelegate.invokeTask (http://localhost/dist/form/polyfills.bundle.js:7778:36)
    at Zone.runTask (http://localhost/dist/form/polyfills.bundle.js:7546:47)
    at HTMLAnchorElement.ZoneTask.invoke (http://localhost/dist/form/polyfills.bundle.js:7841:38)

Stacktrace.js 无法定位 bundle 文件及其对应的 source map，因为无法加载该路径

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

有人在使用 WebPack、Stacktrace.js 并让源映射正常工作吗，或者有人知道如何解决这个问题吗？

Answer 1

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

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