Vscode-ng-language-service: Error for getTemplateReferences (cannot read property 'name' of null)

[mateuszwitkowski]

Hi! I have similiar issue to #182 (another TypeError though). Unfortunatelly, for now Angular Language Service doesn't work for me at all. Here's the error message I'm getting.

Angular Language Service: 5.0.0-beta.5
TypeScript: 2.4.2

Same here.... :(

Same here, the following error appeared during Angular 5 update:

Search path: (...)/src/app/billing/core/cc-process/services
Failed to read JSON file (...)/node_modules/@angular/common/locales/fr.metadata.json
Config file name: (...)/tsconfig.json

Any fix? I have the same problem with language service 5.0.2 too

[OysteinAmundsen]

Same here.

Just for kicks, I edited the ~\.vscode\extensions\Angular.ng-template-0.1.7\server\node_modules\@angular\language-service\bundles\language-service.umd.js:21438 and placed a

console.log(filePath);

in there. That actually gave me a Failed to read JSON file pointing to my projects node_modules/@angular/common/locales/nb.metadata.json. Rightly so, this file does not exist. It seems it tries to read out my current locale to fetch some translations or whatnot, and fails miserably.

I don't know if this is a bug in @angular/language-service or in the vscode extension though. Next part of the original error message, points to ~\.vscode\extensions\Angular.ng-template-0.1.7\server\editorServices.js:797, which just tries to build a map of all templates in the current project.

Any fix? Same here...
