Lost Bot Member due to Cache Options?

Bit of a biggie, I had an error: TypeError: Cannot read properties of null (reading 'bitfield') In this code: 
channelToMessage.permissionsFor(
  client.guilds.cache.get(guildId).members.me
).bitfield
channelToMessage.permissionsFor(
  client.guilds.cache.get(guildId).members.me
).bitfield
I think it's because I changed my caching to: 
  makeCache: Options.cacheWithLimits({
    MessageManager: 5,
    GuildMemberManager: 5,
    PresenceManager: 5,
  }),
  makeCache: Options.cacheWithLimits({
    MessageManager: 5,
    GuildMemberManager: 5,
    PresenceManager: 5,
  }),
I suspect this lost me the bot Member in the cache...? and thus members.me So I've updated to: 
  makeCache: Options.cacheWithLimits({
    MessageManager: 5,
    GuildMemberManager: {
      maxSize: 5,
      keepOverLimit: ({ id }) => id === CLIENT_ID
    },
    PresenceManager: 5,
  }),
  makeCache: Options.cacheWithLimits({
    MessageManager: 5,
    GuildMemberManager: {
      maxSize: 5,
      keepOverLimit: ({ id }) => id === CLIENT_ID
    },
    PresenceManager: 5,
  }),
Does this all checkout to anyone, I have applied this change but am curious if this could have happened in the firdt place. If not, whst caused the error? 🤔

That's a good question, what does <Channel>.permissionsFor(null/undefined) return 🤔 I guess it would return null also...

Yes, it would return null if something that is not a RoleResolvable/UserResolvable is not passed
