   # Description
   
   Want to avoid noisy NPE on core info variables since we already log.warn on line 330.
   
   # Solution
   
   Minor fix: add null checks on the core info variables, as we've seen on ZK restarts that these are unavailable. 
   
   # Tests
   
   Ran IndexSizeTrigger test locally and it succeeded. Didn't add tests for this.
