Summary

Without commit, if the local cache file is holding NIL for some reason, then the
resulted cache data used is nil as well.

This commit fixes by revoking the cache when the list of objects read from it is empty.

Test Plan

Tested locally with file with NIL instead of actual data (i had the case for whatever reason).
Then trigger back the get-objects function and this file got overwritten with actual data.
