Member intents in the developer portal were enabled already, but not in the DiscordSocketConfig

So i added "Gateway.Intents = GatewayIntents.All" ot the config and its working now

Not working:

While it is possible to implement this task using a background script, a simpler and better solution is to do everything in the content script.

The content script can make changes to DOM immediately and it can make a network request to the current site's URL to fetch user's details. The network request will be asynchronous though, otherwise it would introduce unpleasant delays in page loading.

Here's the overall scheme:

1. The content script loads at document_start when DOM is empty.
2. It reads the previously stored data about the users it already checked in the past. The best storage here would be the site's own window.localStorage because it's synchronous and belongs to the same internal tab process so it's fast to read.
3. Use MutationObserver to detect the elements added while the page loads as well as afterwards to support the new reddit UI (it constructs the page dynamically) and various userscripts/extensions that automatically expand the threads in the old reddit UI.
4. For each matching element get the cached data.
5. If absent, make a network request, apply the result, store it in the storage.

You need $expr.

With the help of @LukeWoodward, I did find my mistake and that upd.getChatMember() was the one responsible for giving me the null pointer exception.

upd.getChatMember() will be null if the messages are coming from direct DMs in Telegram and not from group chats. For that, you need to use upd.getMessage().getFrom().getId() for getting the user's id who direct messaged your bot.

You can use TextChannel.createMessageCollector.

It creates a message collector at the channel, collects MESSAGES_TO_COLLECT messages that satisfies filter for SECONDS_TO_REPLY seconds, and when finished, emits end event.

You can also use collect event to do something when a message is collected. However, in this case, we collect only one message, so no need to use collect event.

So the code would be:

The voice state cache is directly linked to the member cache. Since you disabled all the member caching with createLight, the voice states attached to those members will also not be cached properly.

You need to enable voice member cache via setMemberCachePolicy(MemberCachePolicy.VOICE) on your JDABuilder instance.

You never have to guess how to use a library - that's what documentation is for. Any library worth its salt has documentation listing every single class, method, and the property you need to worry about.

A quick google search for "discord-jda docs" takes us to the JavaDoc: https://ci.dv8tion.net/job/JDA/javadoc/index.html

You want to send a message to a user, right? So let's use the search bar and find User. First result under Types is net.dv8tion.jda.API.entities.User. We're now at https://ci.dv8tion.net/job/JDA/javadoc/net/dv8tion/jda/api/entities/User.html

If you want to know how to do something with a user, we look at the Methods every User has. Two catch my eye right away: User.hasPrivateChannel() and User.openPrivateChannel(). We'll click the second one since it looks relevant.

Lo and behold, the docs have example usage! I'll quote it below:

The trick is walking the JSON tree and examining each node to determine if it is a BooleanNode or not.

This code will produce a List of node names that are of BooleanNode type AND have a true value:

Your clients is likely a vector of ClientInfo, so in a const-qualified member-functions, the type of client (in the loop) is const ClientInfo&. When you take the address &client, you get a const ClientInfo*, which cannot be converted to a ClientInfo*.

When you remove the const-qualifier, everything works fine because client is then ClientInfo&.

To fix the issue, change the return-type of the function and declaration of vec to std::vector.
