Magento – magento2 get product image url in model

imagemagento2product

I have a model which returns data to pool interface for section.
Problem is that I'm not able to get product image URL with helper in this model, it always returns placeholder thumbnail URL instead of real image URL.

This is content of my class:

use \Magento\Catalog\Model\CategoryFactory;
use \Magento\Catalog\Helper\Image;


class UpsellProducts
{

    protected $categoryFactory;
    protected $imageHelper;


    public function __construct(
        CategoryFactory $categoryFactory,
        Image $imageHelper
    ) {
        $this->categoryFactory = $categoryFactory;
        $this->imageHelper = $imageHelper;
    }


    public function getCategory($id)
    {
        $category = $this->categoryFactory->create()->load($id);

        return $category;
    }

    public function getProductsCollection($id)
    {
        $r = array();
        $products = $this->getCategory($id)->getProductCollection()->addAttributeToSelect('*')->setPageSize(3);

        $products->getSelect()->orderRand();

        $products->load();

        $image = 'product_small_image';// or 'category_page_list';



        foreach ($products as $product) {
            $r[] = $product->getData();
            $r['image'][] = $this->imageHelper->init($product, $image)->getUrl();
        }

        return $r;
    }

    public function getUpsellProducts()
    {
        //        @TODO category id from BE config
        $t = $this->getProductsCollection(876);

        return $t;
    }
}

I'm using default Image helper and loading 3 random products from category, when I try to get image for this product, I get thumbnail placeholder URL instead of product image.
