okie~ so i was able to figure it out~ since i used notion's slug for dynamic page.
there's this weird thing i noticed -
so here im using
"jp/joqnix/livestreams/stream-summary/" + system.params.slug
so in the href field it shows the correct link -
jp/joqnix/livestreams/stream-summary/17-7-24
( so it populated the slug data too.
if testing from preview it shows the correct url -
but when published to live site - idk why the url structure is doubled like this -
https://onaixia.com/jp/joqnix/livestreams/stream-summary/jp/joqnix/livestreams/stream-summary/20-7-24
