Angular requires a platform to be initialized. This error is thrown when bootstrapApplication is used on the server without providing a BootstrapContext.
When using server-side rendering, bootstrapApplication requires a BootstrapContext to be passed as an argument.
Debugging the error
To resolve this error, ensure that your main.server.ts file correctly passes a BootstrapContext to the bootstrapApplication function.
import {bootstrapApplication, BootstrapContext} from '@angular/platform-browser';import {App} from './app/app';import {config} from './app/app.config.server';const bootstrap = (context: BootstrapContext) => bootstrapApplication(App, config, context);export default bootstrap;
