In my project I’ve got a similar warning: Warning:(1, 1) Angular Language Service internal globalError: Cannot read property 'has' of undefined

Same here with 2.4.9 (both angular core and language service)

Seems an upgrade to LS 4.0.0 did not fix the issue

Node 7.5.0 Typescript 2.2.1 Angular 4.0.0 Angular LS 4.0.0

I changed it to 2.1.5 but still get globalErrors

Warning:(1, 1) Angular Language Service internal globalError: Cannot read property ‘hasOwnProperty’ of undefined Warning:(1, 1) Angular Language Service internal globalError: Cannot read property ‘__constructor’ of undefined

Updating to angular & language service from 4.0.1 to 4.0.2 solved it for me:

@angular/language-service: 4.0.2 typescript 2.2.2 node: 6.10.0 os: mac os IntelliJ 2017.1
