X_SEO_CARD_ROUTE_UNKNOWN
Means
og.capture names a path no site/ route answers
Typical cause
a route's meta declares og: { capture: '/og/…' } and no page.tsx under apps/web/site/ matches that path, so the build has no page to photograph
Fix
x routes --json — list the site/ routes; add apps/web/site/<the capture path>/page.tsx at 1200 x 630 with robots: { index: false }, or correct the og.capture path
