Jhipster Karma UI tests fail on ' Should call create service on save for new entity'

I'm running my ui test with Karma on Jhipster with "yarn test" command.

My tests run normal, but in one of my "dialog component" tests, i have this error.

Component Tests Project Management Dialog Component save Should call create service on save for new entity FAILED

I did my reasearch on google about this error but i couldn't find anything. The message it's pretty clear, it should call create method on service.

This is my code on "save()" method on project-dialog.component.ts:

save() {
    this.isSaving = true;
    if (this.project.id !== undefined) {
        this.subscribeToSaveResponse(
            this.projectService.update(this.project));
    } else {
        this.subscribeToSaveResponse(
            this.projectService.create(this.project));
    }
}

And my project-dialog.component.spec.ts Test code for that part is:

it('Should call create service on save for new entity',
            inject([],
                fakeAsync(() => {
                    // GIVEN
                    const entity = new Project();
                    spyOn(service, 'create').and.returnValue(Observable.of(new HttpResponse({body: entity})));
                    comp.project = entity;
                    // WHEN
                    comp.save();
                    tick(); // simulate async

                    // THEN
                    expect(service.create).toHaveBeenCalledWith(entity);
                    expect(comp.isSaving).toEqual(false);
                    expect(mockEventManager.broadcastSpy).toHaveBeenCalledWith({ name: 'projectListModification', content: 'OK'});
                    expect(mockActiveModal.dismissSpy).toHaveBeenCalled();
                })
            )
        );

I don't know why is this test failing, does anyone has an idea?

Thanks in advance!
