激活路由时无法加载角度联合模块

Question

I am trying to achieve a very simple module federation with shell (host) and travel (remote). Whenever I try do dynamically load the AbcModule from travel I get the following error in the shell:

ERROR Error: Uncaught (in promise): TypeError: Cannot read properties of undefined (reading 'init') TypeError: Cannot read properties of undefined (reading 'init') at angular-architects-module-federation-runtime.js:26:1 at Generator.next () at fulfilled (tslib.es6.js:73:43) at _ZoneDelegate.invoke (zone.js:372:1) at Object.onInvoke (core.mjs:25634:33) at _ZoneDelegate.invoke (zone.js:371:1) at Zone.run (zone.js:134:1) at zone.js:1275:1 at _ZoneDelegate.invokeTask (zone.js:406:1) at Object.onInvokeTask (core.mjs:25621:33) at resolvePromise (zone.js:1211:1) at zone.js:1118:1 at fulfilled (tslib.es6.js:73:86) at _ZoneDelegate.invoke (zone.js:372:1) at Object.onInvoke (core.mjs:25634:33) at _ZoneDelegate.invoke (zone.js:371:1) at Zone.run (zone.js:134:1) at zone.js:1275:1 at _ZoneDelegate.invokeTask (zone.js:406:1) at Object.onInvokeTask (core.mjs:25621:33)

app routes from shell:

import { loadRemoteModule } from "@angular-architects/module-federation";
import { Routes } from "@angular/router";

export const APP_ROUTES: Routes = [

      remoteName: 'travel',
      exposedModule: './Module'
    })
    .then(m => m.AbcModule)
  }
];

webpack.config.js from shell:

const mf = require("@angular-architects/module-federation/webpack");
const path = require("path");
const share = mf.share;

          ...sharedMappings.getDescriptors()

    }),
    sharedMappings.getPlugin()
  ],
};

AbcModule from travel:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { AbcComponent } from './abc/abc.component';
import { RouterModule } from '@angular/router';

@NgModule({
  declarations: [AbcComponent],
  imports: [CommonModule, RouterModule.forChild([
    {
      path: '',
      component: AbcComponent
    }
  ])],
  exports: [RouterModule]
})
export class AbcModule {}

I got it working by changing the loadRemoteModule parameter to this:

import { loadRemoteModule } from "@angular-architects/module-federation";
import { Routes } from "@angular/router";
import { TestComponent } from "./test/test.component";

export const APP_ROUTES: Routes = [
  {
    path: '',
    component: TestComponent,
    pathMatch: 'full'
  },
  {
    path: 'abc',
    loadChildren: () => loadRemoteModule({
      remoteEntry: 'http://localhost:4201/remoteEntry.js',
      type: 'module',
      exposedModule: './Module'
    })
    .then(m => m.AbcModule)
  }
];
