Can't bind to 'node' since it isn't a known property of 'router-outlet'.

1) Grab the "node" data from the server, from within the parent component
2) Pass the data I have retrieved from the server into the child router-outlet

@Injectable()
export class SharedService {

    sharedNode = {
        // properties, e.g
        //id: '' and so on...
    };
}

this.sharedService.sharedNode = this.node;

node: Node;

ngOnInit() {
    this.node = this.sharedService.sharedNode;
}
