In the product catalog, by clicking the Variants button, nothing is displayed

I have a created item item that has manufacturer-based options.
After creating a website item - the page is displayed on the site, in the product catalog, but nothing is displayed by clicking the Options button.


where to look and what to do?

What version are you on? This should be fixed in V13.13.0
