forkJoin已被弃用,用于多个可观察函数

首先,我有多个这样的服务文件=>

服务1.ts

Patch(updateobject:object,id:number): Observable<MyObject> {    
    return this.http.patch<MyObject>(`${this.MyObject_API}/${id}`,  JSON.stringify(updateobject),{headers:{'Content-Type': 'application/json'}})           
   }

服务2.ts

Patch(updateobject:object2,id:number): Observable<MyObject> {    
    return this.http.patch<MyObject>(`${this.MyObject2_API}/${id}`,  JSON.stringify(updateobject),{headers:{'Content-Type': 'application/json'}})           
   }

我试着像=>

forkJoin(service1.patch(),service2.patch()).subscribe(([call1response,call2response])....

但是为什么 forkJoin 是删除和显示 forkJoin 是否已弃用?

消息=>

(v1: ObservableInput<MyObject>, v2: ObservableInput<MyObject>): Observable<[MyObject, MyObject]>' is deprecated
