angular 9.0.0-rc.2 Cannot read property 'onDestroy' of undefined

[leon]

I'm using nrwl NX and jest.
When I run jest I'm getting

TypeError: Cannot read property 'onDestroy' of undefined


node_modules/@ngneat/until-destroy/bundles/ng:/@ngneat/until-destroy/lib/until-destroy.ts:32:48
at Object.__decorate (../../../../node_modules/tslib/tslib.js:93:99)

Has anything changed in the latests RC's that could cause this to happen?

Update

I forked and updated until-destroy to the latest angular rc release, but the tests work, so it hasn't got anything to do with angular/core.

Nx uses the library jest-preset-angular and nx is currently using version 7.1.1

jest-preset-angular has released a version 8.0.0, but nx still hasn't updated to that version, so that might fix it.

The only thing i can think of is that jest-preset-angular doesn't compile to ivy code and thus ɵcmp will be null.

But I'm not sure how to get around it, or if I just have to wait for nx to catch up to angular 9. :(

Hi, this is our peer dependencies requirements:

"peerDependencies": {
  "@angular/core": ">=9.0.0-next.10"
}

So I guess you'll have to wait or use the older version.

I have some issue when try run my app in storybook. I can't use old version, because i use Ivy.

This lib really useful, but we had to remove because of this bug.

We have the same issue in storybook using Ivy

For some reason, Storybook doesn't use Angular Ivy with my setup and I had the same error. I added postinstall script with ngcc option to package.json according to the official docs and now everything works well.
After making these changes you may need to delete node_modules (rm -rf) and install them again.

P.S. to check if Ivy enabled you can import it from angular/core

import { Component, OnInit, ɵivyEnabled as ivyEnabled, OnDestroy } from '@angular/core';

ngOnInit(): void {
    console.log('ivyEnabled', ivyEnabled);
}
