When using Angular Universal with AWS Lambda Edge, the component cannot be resolved.

Did you run and wait for 'resolveComponentResources()'?

We are running "build:serverless:deploy". Detailed commands are:

"build:serverless": "npm run build:browser:serverless && npm run build:server:serverless",
"build:serverless:deploy": "npm run build:serverless && npm run deploy",
"deploy": "serverless deploy",

This is our AuthComponent.

import { Component} from '@angular/core';

@Component({
    selector: 'kt-auth',
    templateUrl: './auth.component.html',
    styleUrls: ['./auth.component.scss'],
})
export class AuthComponent {
    today: number = Date.now();
}

We are using Angular 11.
