During the process of downgrading a component, the @ContentChild(TemplateRef) becomes null

When utilizing this code within any component:

@ContentChild(TemplateRef) public myTemplate: TemplateRef<any>;

It functions properly in Angular 2, I can access it with:

this.myTemplate

However, after downgrading the component to make it compatible with AngularJS 1.6.2, the value is:

this.myTemplate // undefined

Do I need to make any adjustments during the downgrade process? Is there something specific that needs to be added to my constructor?
