Fatal error caused by woocommerce on sales page

What is the correct shortcode for “sale” page in woocommerce?

I have used this: [sale_products per_page=”12″]
But this is not showing sales products now, once trying edit with elementor, page is showing fatal errors.

Found these codes also:
[woocommerce_product_filter_sale]
[woocommerce_product_filter_products]
But these are showing up only the text?

Is this because we need to set sales products again to a schedule date???

The page I need help with: [log in to see the link]
