(dot)Lottie extension Animations don't load on code export

I have noticed that upon exporting code from webflow to Hostinger (linux hosting) which includes the animation files,

The .lottie extension animations are not working anymore, however .json extension lotties are working fine.

Here is the link -

Webflow version - https://boat-watch.webflow.io/

Exported version - https://metaminds.studio/Portfolio_watch/index.html

Only the scroll based animations (which were in .lottie) are no longer visible.
So either this is happening because they are scroll based or because they are in .lottie extension.

I have noticed people have encountered similar problem before in the forum, but couldn’t find a solution that worked for me.

PS - Someone mentioned adding a special id tag from webflow, but couldn’t understand it.
