Angular V17-SSR-ERROR Error: NullInjectorError: No provider for WrappedSocket

I have upgraded Angular to V17 with SSR and when i tried to load page this error is coming. R3InjectorError(Standalone[_HomeComponent])[_SocketService -> _SocketService -> _SocketService -> WrappedSocket -> WrappedSocket]: NullInjectorError: No provider for WrappedSocket!

Note: - i can not add this inside modules because i am working with SSR Standalone components only.

Need help to resolve this issue by adding these inside providers or by using service.ts

Because i can not make use of Modules in angular 17 I have Created new Service with extends Socket method and and then impored this new service to my exsiting service.

before

app.module.ts
......................................................................
const config: SocketIoConfig = { url: environment.SOCKET_API, options: {} };
@NgModule({
imports: [
SocketIoModule.forRoot(config),
]
})
......................................................................
socket.service.ts
......................................................................
private socket = inject(Socket)
export class SocketService {

  online(id: string){
    this.socket.connect(id);
  }
}
......................................................................

After

ngx-socket.service.ts
......................................................................

const config: SocketIoConfig = { url: environment.SOCKET_API, options: {} };

@Injectable({
  providedIn: "root",
})
export class NgxSocketService extends Socket {
  constructor() {
    super(config);
    this.disconnect();
  }
}
......................................................................
socket.service.ts
......................................................................
import { NgxSocketService } from "./ngx-socket.service";
private socket = inject(NgxSocketService);

@Injectable({
  providedIn: "root",
})
export class SocketService {
private socket = inject(NgxSocketService);
constructor() {
    afterNextRender(() => {
      const senderId = this.jwtService.getUserId();
      if (senderId) {
        this.connect(senderId);
      }
    });
  }
}
}
