Sveltekit with caching started to received 404 after some time.

So i build sveltekit app using cloudflare adapter. Everything was working fine but at some point I wanted to enable caching from worker (config on screenshot). Then I went offline for 2 hours. After 3 hours i got notified that app is dead when trying to reload dynamic imports. I purged the cache and then rollback caching implementation. I 've got two many requests in console at the time so not sure what is the reason behind this. Is my implementation to access cache invalid ?
