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)

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)
}
];
