Невозможно назначить только для чтения свойство 'stopImmediatePropagation' объекта

Question

После обновления @ angular / platform-browser (и других @ angular / xxx) до версии 6.0.4 у меня возникает эта ошибка при первой загрузке приложения и после каждой первой перезагрузки страницы (первая F5: ошибка, вторая F5: работа):

NodeInvocationException: Невозможно назначить только для чтения свойство 'stopImmediatePropagation' объекта '[объект Object]' TypeError: Невозможно присвоить только для чтения свойство 'stopImmediatePropagation' объекта '[объект Object]'at DomEventsPlugin.module.exports ../ node_modules/@angular/platform-browser/bundles/platform-browser.umd.js.DomEventsPlugin.patchEvent (I: \ Progetti \ Platform \ Software \ CTAgenda \ ClientApp \ dist \ vendor.js: 60044: 50) в новом DomEventsPlugin (I: \ Progetti \ Platform \ Software \ CTAgenda \ ClientApp \ dist \ vendor.js: 60031: 15) в eval (ng: ///AppModule/module.ngfactory.js: 51: 25) в _callFactory (I: \ Progetti \ Platform \ Software \ CTAgenda \ ClientApp \ dist \ vendor.js: 40373: 28) в _createProviderInstance $ 1 (I: \ Progetti \ Platform \ Software \ CTAgenda \ ClientApp \ dist \ vendor.ЯШ: 40319: 26на: 29) в _createProviderInstance $ 1 (I: \ Progetti \ Platform \ Software \ CTAgenda \ ClientApp \ dist \ vendor.js: 40316: 26) в resolNgModuleDep (I: \ Progetti \ Platform \ Software \ CTAgenda \ ClientApp \ dist \ vendor).js: 40282: 21) в _createClass (I: \ Progetti \ Platform \ Software \ CTAgenda \ ClientApp \ dist \ vendor.js: 40352: 32)

Это код в моем vendor.jsгде генерируется ошибка:

DomEventsPlugin.prototype.patchEvent = function () {
    if (!Event || !Event.prototype) {
        return;
    }
    if (Event.prototype[stopMethodSymbol]) {
        // already patched by zone.js
        return;
    }
    var delegate = Event.prototype[stopMethodSymbol] =
        Event.prototype.stopImmediatePropagation;
    Event.prototype.stopImmediatePropagation = function () { <-- ERROR
        if (this) {
            this[stopSymbol] = true;
        }
        // should call native delegate in case
        // in some environment part of the application
        // will not use the patched Event
        delegate && delegate.apply(this, arguments);
    };
};

Это моя среда

• .NET Core 2.1
• Угловой 6.0.4
• Угловой /Cli 6.0.8
• Webpack 4.12.0
• aspnet-prerendering 3.0.1
• aspnet-webpack 3.0.0

В режиме разработкиу меня активировано промежуточное программное обеспечение разработчика webpack, может ли ошибка быть связана со временем создания поставщика?Первый раз, когда приложение создает поставщика, второй раз, когда поставщик берется из кеша:

У меня такая же проблема.Попробуй изменить

DomEventsPlugin.prototype.patchEvent = function () {
    if (!Event || !Event.prototype) {
        return;
    }
    if (Event.prototype[stopMethodSymbol]) {
        // already patched by zone.js
        return;
    }
    var delegate = Event.prototype[stopMethodSymbol] =
        Event.prototype.stopImmediatePropagation;
    Event.prototype[stopMethodSymbol] = function () {  <-- CHANGE
        if (this) {
            this[stopSymbol] = true;
        }
        // should call native delegate in case
        // in some environment part of the application
        // will not use the patched Event
        delegate && delegate.apply(this, arguments);
    };
};
