Angular 2+ Path to ErrorHandler error.stack

I'm trying to use stacktrace.js to report errors, but the path in the stack trace refers to "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)

Stacktrace.js cannot find the package file and the corresponding source map because this path could not be loaded

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

      

        
        
        
      

    

Does anyone use WebPack, Stacktrace.js and get the source maps to work, or does anyone know how to fix this issue?
