Can anyone help me to fix this issue?
CodePudding user response：
I can see that you missed importing BrowserTransferStateModule could that be the issue?
@NgModule({
declarations: [AppComponent],
imports: [
BrowserModule.withServerTransition({ appId: 'serverApp' }),
BrowserTransferStateModule,
CoreModule,
// code omitted
],
bootstrap: [AppComponent],
})
export class AppModule {}
