You need to specify the events which you want your bot to receive using gateway intents.

Instead of

const client = new Discord.Client();

Use

const client = new Discord.Client({ intents: [Enter intents here] })

For example

const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] })

You can access the command line arguments from anywhere in your code using the Environment class.

In particular, you can use Environment.GetCommandLineArgs:

When exactly does segmentation fault happen (=when is SIGSEGV sent)?

When you attempt to access memory you don’t have access to, such as accessing an array out of bounds or dereferencing an invalid pointer. The signal SIGSEGV is standardized but different OS might implement it differently. "Segmentation fault" is mainly a term used in *nix systems, Windows calls it "access violation".

Why is the process in undefined behavior state after that point?

Because one or several of the variables in the program didn’t behave as expected. Let’s say you have some array that is supposed to store a number of values, but you didn’t allocate enough room for all them. So only those you allocated room for get written correctly, and the rest written out of bounds of the array can hold any values. How exactly is the OS to know how critical those out of bounds values are for your application to function? It knows nothing of their purpose.

Furthermore, writing outside allowed memory can often corrupt other unrelated variables, which is obviously dangerous and can cause any random behavior. Such bugs are often hard to track down. Stack overflows for example are such segmentation faults prone to overwrite adjacent variables, unless the error was caught by protection mechanisms.

If we look at the behavior of "bare metal" microcontroller systems without any OS and no virtual memory features, just raw physical memory - they will just silently do exactly as told - for example, overwriting unrelated variables and keep on going. Which in turn could cause disastrous behavior in case the application is mission-critical.

Why is it not recoverable?

Because the OS doesn’t know what your program is supposed to be doing.

Though in the "bare metal" scenario above, the system might be smart enough to place itself in a safe mode and keep going. Critical applications such as automotive and med-tech aren’t allowed to just stop or reset, as that in itself might be dangerous. They will rather try to "limp home" with limited functionality.

Why does this solution avoid that unrecoverable state? Does it even?

That solution is just ignoring the error and keeps on going. It doesn’t fix the problem that caused it. It’s a very dirty patch and setjmp/longjmp in general are very dangerous functions that should be avoided for any purpose.

We have to realize that a segmentation fault is a symptom of a bug, not the cause.

macOS Monterey introduced AirPlay Receiver running on port 5000. This prevents your web server from serving on port 5000. Receiver already has the port.

You can either:

1. turn off AirPlay Receiver, or;
2. run the server on a different port (normally best).

Turn off AirPlay Receiver

Go to System Preferences → Sharing → Untick Airplay Receiver.

See more details

You should be able to rerun the server now on port 5000 and get a response:

You are trying to use the python (alias) library instead of python3.

Try to use apk update && apk upgrade && apk add python3 instead.

When I installed VS2022 preview 4, my configuration became C:\Program Files\Microsoft\jdk-11.0.10.9-hotspot

This can be fixed for you if you run the maui-check command (if you installed that component during visual studio installation).

If you don't have the maui-check tool, you can get it by running the dotnet tool install -g Redth.Net.Maui.Check command

Maybe you skipped a step during installation and that's why you get the error.

Have you made sure that the 'applications.commands' scope is checked in the scopes section of the OAuth2 settings for your bot in the discord developer portal?

After changing these settings it seems to work fine. I downloaded sdk version 30 from sdk manager.

android { compileSdkVersion 30 buildToolsVersion "30.0.3" defaultConfig { applicationId "com.anurag.myapplication" minSdkVersion 23 targetSdkVersion 30 versionCode 1 versionName "1.0" testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" }

Ahaha it worked! this is so awesome! Yes just follow the tutorial and for me that was doing go mod init test3 to create a module. No one else has been upgrading from old version or everyone else just understood it properly I guess.
