If I change this code: to this code (&& node.parent): It works like a charm.

I don’t know if it’s a problem from tsserver or ng language server

Yeah, please see https://github.com/angular/vscode-ng-language-service#versioning. Until the extension and the language service are on 3.9 it won’t work. But I think we can update to 3.9 now.
