NgRX的角度错误-实体类型[x]没有EntityDefinition

Question

我正在使用一个从Angular 8到10的应用程序，似乎我搞砸了什么。我有几个解析器，其中一个给了我一个错误。我不知道造成问题的实体或数据服务有什么不同。我也不确定这个错误消息声称丢失了什么，它应该在哪里

Uncaught (in promise): Error: No EntityDefinition for entity type "makVersion".

这是有问题的功能模块。

// NgRX related metadata for NgData
const entityMetadata: EntityMetadataMap = {

@NgModule({

entityDataService.registerService('signoffReq', signoffReqDataService);
entityDataService.registerService('makProject', makProjectDataService);
entityDataService.registerService('makVersion', makVersionDataService);
}
}

存储是app.module

StoreModule.forRoot(reducers, {
metaReducers,
runtimeChecks : {
strictStateImmutability: true,
strictActionImmutability: true,
strictActionSerializability: true,
strictStateSerializability:true
}
}),
StoreDevtoolsModule.instrument({maxAge: 25, logOnly: environment.production}),
EffectsModule.forRoot([]),
EntityDataModule.forRoot({}),
StoreRouterConnectingModule.forRoot({
stateKey: 'router',
routerState: RouterState.Minimal
}),
StoreModule.forRoot({}, {}),
StoreDevtoolsModule.instrument({ maxAge: 25, logOnly: environment.production })

这是解析器。"；这里"；则不输出日志。

/*
This is the resolver for the mak version models. The function that it
calls pulls down all of the versions created by a user.
*/

// Common Angular Items
import { Injectable } from '@angular/core';
import { ActivatedRouteSnapshot, Resolve, RouterStateSnapshot } from '@angular/router';

// RxJS Items
import { Observable } from 'rxjs';
import { filter, first, map, tap } from 'rxjs/operators';

// The mak version entity service
import { makVersionEntityService } from '../services/entity/makVersion-entity.service';

@Injectable()
export class MakVersionsResolver implements Resolve<boolean> {
constructor(private makVersionEntityService: makVersionEntityService) {
}
resolve(route: ActivatedRouteSnapshot,
state: RouterStateSnapshot): Observable<boolean> {
console.log('Here');
return this.makVersionEntityService.loaded$
.pipe(
tap(loaded => {
if (!loaded) {
this.makVersionEntityService.getAll();
}
}),
filter(loaded => !!loaded),
first()
);
}
}

因此，很明显，当我通过CLI添加组件时，它将这些组件添加到主应用程序，而不是功能应用程序。我一定错过了这一点，并手动将组件添加到功能应用程序中。第二个声明的存在导致了导致此错误的一些问题。我的猜测是，它试图解析与主应用程序中的这些组件相关的解析器，但显然没有包含实体。
