Discord.js: ReactionCollector only collects reactions from Users that have already sent a message in the Channel.

[Volterium]

I'm setting up a ReactionCollector on a message like this:

const filter = (reaction, user) => {
    return true; 
};
const collector = msg.createReactionCollector(filter);
collector.on('collect', (reaction, user) => {
    console.log('Callback - User:' + user.id)
});

I would expect that this would print Callback - User: foo when a user with the UserID foo reacts to msg.
However, this only happens if the User has already sent a message in the Channel after msg was sent.

Caused by API intents - #4961.

Thanks for the reply. It's not obvious to me which of my functions requires those privileges. Could you elaborate?

I also have the same issue. I don't see how that's related to privileges though . . .

You don't need privileged intents for that, you just need to enable necessary partials in ClientOptions.

I see, so I would imagine that in this particular scenario, the "REACTION" string needs to be added to the array in the partials attribute of the Client. Thanks a lot!

It would be good if you could also add a warning about this on the documentation of classes like ReactionCollector (https://discordjs.guide/popular-topics/collectors.html#reaction-collectors).
