The expression parent::fieldRender(); of type string|Illuminate\View\View|Illuminate\Contracts\View\Factory adds the type Illuminate\Contracts\View\Factory to the return on line 40 which is incompatible with the return type declared by the interface Illuminate\Contracts\Support\Renderable::render of type string.
