hey i have exact the same error on same position in preview-sdk-service.js i reinstalled everything with no errors but still the same. i contacted the support, when i get an answer i will let you know. i have also problems with playground today it will not load correctly on my device. btw yesterday it worked like a charm.

---------SUPPORT ANSWER--------------

"we are migrating the auth to use Firebase and looks like couple things are still propagating. An engineer is working on this and should be resolved by Monday"

so its not a user mistake and we can just wait and hope they can fix it quickly.

I'm running into this exact issue at the moment. Even started a new template using the Angular CLI command:

ng new --collection=@nativescript/schematics my-mobile-app

From the site:

Angular CLI support

The initial template seem to work but after adding some custom modules this started happening. Running on a Android Virtual Device works.

I've been looking for a solution and the issues seems to ga back as far as 2018 so i'm not sure if this is even een NativeScript issues of a dev environment issues not being setup correctly.
