fetchLogs return null executor

Question

I want to fetch audit logs entries with my bot, so i use fetchAuditLogs(), it return me everything

But when i use makeCache method in client options and i put UserManager: 0, the function will return executor: null, so my question is

How can i get the executor id without caching every members, also if the user is not cached it also return null.

const client = new Client({
 makeCache: Options.cacheWithLimits({
        UserManager: 0
    }),
});

const audit = guild.fetchAuditLogs()
const { executor } = audit.entries.first()
