title: PDP page gets redirected to 404 for some products
body: <p>I need some help with this issue in Vue Storefront that I have had some difficulty trying to solve:</p>
  
  <p>After navigating to PDP(Product Detail Page) and refreshing the page, the page gets redirected to ‘page-not-found’ for many products. The products that get redirected to page-not-found are always the same and not all products get redirected to page-not-found. Traversing to the PDP using router-link works, even when the path is hardcoded, but navigating directly to it or refreshing the page while on a PDP doesn’t work. I also tried isolating the problem and found that even including just the Product.js mixin file from the core and removing all other code on PDP still causes the redirect.</p>
  
  <p>I am unable to solve this bug despite trying for days. Even if you can’t see what is causing the issue, it would be helpful if anyone can at least show me how to debug this issue. I don’t know how to know what code is causing the redirect to 404.</p>
  
  <p>Thanks</p>
