After Angular 6 Update this._zone.onMicrotaskEmpty undefined

Question

after updating application to angular 6 I get errors during test execution

TypeError: Cannot read property 'subscribe' of undefined
        at new ApplicationRef node_modules/@angular/core/fesm5/core.js:4322:1)
        at _createClass node_modules/@angular/core/fesm5/core.js:8126:1)
        at _createProviderInstance$1 node_modules/@angular/core/fesm5/core.js:8088:1)
        at initNgModule node_modules/@angular/core/fesm5/core.js:8024:1)

        at NgModuleFactory_.push.../node_modules/@angular/core/fesm5/core.js.NgModuleFactory_.create node_modules/@angular/core/fesm5/core.js:11263:1)

It says, that

this._zone.onMicrotaskEmpty

is undefined.

My test executes some code running outside angular with

this._ngZone.runOutsideAngular();

Does someone know how to solve this problem?

have you updated the zone.js package as well ? – Sh. Pavel Jun 18 '18 at 08:27 — Sh. Pavel, Jun 18 '18 at 08:27

if you call this._ngZone.runOutsideAngular();, it will not inside ngZone, so you will not get this._zone.onMicrotaskEmpty. This emitter will only fire inside ngZone.
