Unable to create Custom Angular Element

1 answer

I am creating a custom Component which is being registered to module like this.

app.module.ts

import { createCustomElement } from "@angular/elements";  @NgModule({   declarations: [ExtensionComponent],   entryComponents: [ExtensionComponent],   imports: [BrowserModule],   bootstrap: [] }) export class AppModule {   constructor(private injector: Injector) {   }    ngDoBootstrap() {     const extension = createCustomElement(ExtensionComponent, { injector: this.injector });     customElements.define('caas-extension', extension);   } } 

For this i am getting an error in the last line where i define the custom element "extension".

Error

Argument of type 'NgElementConstructor<unknown>' is not assignable to parameter of type 'CustomElementConstructor'. 

I have updated cli version as well as suggested in other answer on the similar issue. Below are my version details

Angular CLI: 9.1.0-rc.0 Node: 12.13.0 OS: win32 x64 Angular: 9.1.0-rc.2 

All answers to this question, which has the identifier 60848231

The best answer:

I had same issue. To overcome this issue, I undo my changes on git to updated versions on package.json file and re-updated it with following command: ng update @angular/core --next

I hope this works for you too.
