Google Search Console - Product Snippets

[Craig Day]

After submitting the sitemaps to Google Search Console I get a number of errors regarding Product Snippets.

- Either "offers", "review", or "aggregateRating" should be specified - 286 items.

- Missing field "priceValidUntil" (in "offers"),

Example page that it highlights as invalid: https://www.cashmerestore.co.uk/en/goatskin-cushions-pillows/151-light-grey-goatskin-cushion-45-x-45.html

Site: www.cashmerestore.co.uk

Prestashop Version: 1.7.8.7.

PHP Version: 7.3.29

2 questions - What's causing it and how do I fix it?

What I ended up doing (in case anyone has the same problem) is as follows:

In Themes/<theme_name>/Templates/Catalog/_Partials/Minitures/product.tpl

 Block - product_price_and_shipping

add " itemprop="offers" itemscope itemtype="https://schema.org/Offer" >
          <link itemprop="availability" href="https://schema.org/InStock"/>
        <meta itemprop="priceCurrency" content="{$currency.iso_code|escape:'html':'UTF-8'}">  "

to the end of the div tag so it reads as follows:

     {block name='product_price_and_shipping'}
        {if $product.show_price}
          <div class="product-price-and-shipping" itemprop="offers" itemscope itemtype="https://schema.org/Offer" >
          <link itemprop="availability" href="https://schema.org/InStock"/>
        <meta itemprop="priceCurrency" content="{$currency.iso_code|escape:'html':'UTF-8'}">
            {hook h='displayProductPriceBlock' product=$product type="before_price"}
            <span itemprop="price" class="price">{$product.price|escape:'html':'UTF-8'}</span>
            {if $product.has_discount}
              {hook h='displayProductPriceBlock' product=$product type="old_price"}

              <span class="regular-price">{$product.regular_price|escape:'html':'UTF-8'}</span>
              {*if $product.discount_type === 'percentage'}
                <span class="discount-percentage">{$product.discount_percentage|escape:'html':'UTF-8'}</span>
              {/if*}
            {/if}       
            {hook h='displayProductPriceBlock' product=$product type='unit_price'}
            {hook h='displayProductPriceBlock' product=$product type='weight'}
          </div>
        {/if}
      {/block}
