User reported clicking matrix prices led to 'Произошла ошибка!' on OZON home page. Cause: parsers captured /product/?sponsored=1&cpc=Jtiito95... links that died after few hours. Fix: - ozon.py: skip href with 'sponsored=1', '/promo/', 'cpc='. Strip query string from final URL. - yamarket.py: skip 'sponsored=1', 'cpc=', 'advUuid' (Я.Маркет sponsored marker) - citilink.py: strip query string from final URL (defensive) Now matrix links go to canonical product pages that don't expire.
