Error when adding to cart a product by category page

[ziofonta]

I'm getting this error when, after scrolling the category page, I try to add to cart one product:

{"status":"error","content":"No category provided"}
            <div class="m-fpc-debug-info-small m-fpc-debug-info-not-cacheable">
                <div class="m-fpc-debug-info-main-block-small">
                    <h2 class="m-fpc-hit-info-small">Not cacheable </h2>
            </div>
        </div>

this happens only when trying to add to cart products that are "added" to the page by infinite scroll, the error does not occur when adding the first products already present in the page.
