Discord.js: invalid array length Allocation failed - JavaScript heap out of memory [PRESENCE_UPDATE]

[crxts]

Hello, for a little while I have this error which crashes my bot every ~ 2 days. The presence cache seems to be overloaded which normally should not cause any problems because the bot is only on 500 servers.

I run into the same issue, where presence cache seems to crash the bot every x hours.
My bot is in around 500 servers as well. And I'm looking for an alternative fix since I don't really use presence all that much. Besides when updating my own bot's presence or when fetching a user's presence through my profile command.

So hopefully someone has a potential "fix" or a solution.

https://discordjs.guide/popular-topics/intents use Gateway Intents, and don't supply the privilleged intent GUILD_PRESENCES, or use a machine with more memory

The problem is that I cannot filter Intents, I do not have privileged access and therefore no more access to GUILD_MEMBERS and in terms of memory I have 16gb, I tried to increase the limit via --max-old-space-size but that did not solve the problem

Is your bot verified but denied for the member intent? Later this week, Discord will disable access to privileged intents if you are not whitelisted or have not enabled them in the dev portal, even if you are not specifying intents in your code.

while checking the bot, I skipped the chapter on privileged intents, a nice mistake .. but I just looked at the faq on the discord developers server and it is still possible to request them, so I will do it but unfortunately I need these two Intents.. so I can't turn them off to fix my problem

fixed by upgrading the node version to 12.19.0 .
