Failure Information (for bugs)

 nx generate app                                                 
>  NX   NOTE  Nx didn't recognize the command, forwarding on to the Angular CLI.

? What type of app would like to create? ionic           [Ionic app]
You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array, or Iterable.

Steps to Reproduce

1. npm create-xplat-workspace my-apps. Select empty workspace and Angular CLI.
2. ng g @nstudio/xplat:init. Select arch: Ionic, Angular, prefix: ci
3. nx generate app. Select name: app1, type: Ionic

Result: Error: You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array, or Iterable.

Context

• NX Version 8.4.13
• Xplat Version 8.0.6

A minimal reproduce scenario using allows us to quickly confirm a bug (or point out coding problem) as well as confirm that we are fixing the right problem.

I wondering why this is not tested.

This was extremely helpful thanks all, especially @paullryan !

To anyone else that stumbles upon this (and @NathanWalker). Using ng does work but once you start you must continue to use ng (angular-cli) for all generation and init commands as mixing nx commands for generation will not properly tag angular.json and instead will try to populate the workspace.json which is what causes this error with nx 8.5.1+

so this will work on an existing nx project that is using angular-cli

ng add @nstudio/xplat
ng g @nstudio/xplat:init --prefix=cb --platforms=web,nativescript
ng generate @nstudio/xplat:app app
ng serve nativescript-app
