This logic is in the same block as line #313 and always evaluates to True and thus isn't required (hence the deletion).

SUMMARY
Flask-Caching supports passing in
"null"as the cache type, which resolves to no caching at all (https://flask-caching.readthedocs.io/en/latest/#nullcache). This is preferred to setting the cache toNoneso that we can assume a cache is always initialized and calls tocache.memoize()will never fail.TEST PLAN
