vscode-chrome-debug Failed to load resource ERR_CONNECTION_REFUSED - visual-studio-code

Installed the vscode-chrome-debug extention and attempted to launch an angular.js site. I'm able to connect to the chrome debugger, but accessing any resources via localhost:9009 like /index.html or /json fail to load. Running chrome with developer mode on to disable extensions.
Has anyone dealt with this before? Is this a bug in the extension? If anyone sees anything I'm doing wrong please let me know. Thanks!

›Attempting to attach on 127.0.0.1:9222
Failed to load resource: net::ERR_CONNECTION_REFUSED (http://localhost:9009/index.html)

There's a missing step in my setup... I need to run a web server! Seems obvious but I was under the assumption that the debug extension was doing something under the covers to serve up the site given the static file location.
I setup a gulpfile and task to run a gulp-webserver. I ran the launch task and then launched the debugger and it worked.

Visual code debugger adapter immediately dies when trying to connect to vscode-hack debugger in local launch mode

I am using the vscode-hack extension on visual code studio on macOS Big Sur. My settings.json includes following launch configuration:
"configurations": [
{
"name": "HHVM: Run Script",
"type": "hhvm",
"request": "launch",
"script": "${file}",
"hhvmPath": "/usr/local/bin/hhvm",
"hhvmArgs": ["--mode", "vsdebug", "--vsDebugPort", 8999],
"cwd":"${workspaceFolder}"
}
]
When I try to debug a Hack script in Visual code debugger, Visual code debugger adapter launches and immediately dies. I have verified launching hhvm with the same args from command line, and it works fine. I am following the instructions here https://github.com/slackhq/vscode-hack/blob/master/docs/debugging.md
Does anybody have any suggestions?

Go to Google Chrome File location, let say on Windows 10/11, or even in a shortcut icon -> Right-click -> Properties -> Open File Location.
You will see two applications of the chrome: chrome.exe and chrome_new.exe.
Run the chrome_new.exe and it will delete and replace the previous chrome.exe.
After that, you will now be able to start and use Google Chrome again.

Unable to debug flutter dart code in VS Code, Unverified Breakpoint error

When the code is not running, I can add breakpoint (round red circle), but as soon as it goes into debug mode, it turns into unverified breakpoint (grey hollow circle) and doesn't work at all. However, the same project works well on other systems.
I've no idea what the problem is or what the solution would be.
I've tried reinstalling flutter SDK numerous times, and have gone through a lot of links on SOF and GitHub regarding this, but none has been helpful enough.

i came from mac and always use fn + f5, on windows that means start withouth debugggin, that was my mistake.
"version": "0.2.0",
"configurations": [
{
"name": "Flutter",
"request": "launch",
"type": "dart",
"flutterMode": "debug"
}
]
}
This is my launch.json file ... changing "flutterMode" from profile to debug solved the issue ... if you dont have this line adding it could help.
For anybody running into this problem while trying to debug external libraries or sdk code: Make sure you checked "Dart: Debug External Libraries" and "Dart: Debug Sdk Libraries" under Settings > Extensions > Dart & Flutter as described here.
You can also add the following to your settings.json
"dart.debugExternalLibraries": true,
"dart.debugSdkLibraries": true,
Clicking Run on the top menu in VS code and selecting 'Enable all breakpoints' worked for me. Though you have to place your breakpoint first.
You can also try placing your breakpoint and save your code, then leave the emulator running and close and restart your vs code IDE and run the app with debugging.
For flutter-web I had to change back to <base href="/"> within the web/index.html. A custom href lead to a none-debuggable project.
Navigate to the Run Tab and select Dart & Flutter from the drop down menu, finally hit the play button.
Your main.dart file's path is not specified right.
so in this block
"name": "Dart",
"type": "dart",
"request": "launch",
"program": "bin/main.dart"
please use
"program": "lib/main.dart"
I was also facing the same issue, I am looking for the exact reason but removing the launch.json file worked for me.
Have faced the same issue, resolved by stopping the current active session and click on RUN and select START DEBUGGING. This worked for me.
I faced the same problem with debug in certain dart files, but the other files I could.
Then I realized that it happened when I call another file and this trick would help:
Instead of typing:
import '../form/productdetail.dart';
I replaced with:
import 'package:myapp/form/productdetail.dart';
and it helped.
I had a similar problem. I solved by completely uninstalling and reinstalling Vscode + remove the data. See here
In my case, the parents folder contains special character (#):
.../#Projects/my_project/
Remove the # and the debug goes well:
.../Projects/my_project/
I had a similar problem. My platform is Ubuntu 20.04. I was setting the breakpoint in vscode expecting the vscode debugger to work immediately, but no. After an hour of googling, I hit the Flutter docs on the DevTools page.
To resolve :
Open your flutter project in vscode.
Follow the 'Install from VS Code' section of the docs to install DevTools.
Start your emulator, wait for it to completely load up.
Select Run => Start Debugging.
Check that app is running as expected in the emulator.
Select commandPalette => Dart:Open DevTools => 'Open DevTools in web browser'. The DevTools dashboard opens in a new browser tab.
Select the Debugger tab.
Open the relevent code file and add your breakpoint by clicking the leftmost breakpoint column at the required line.
Progress your app by clicking the emulator UI. Vscode debugger should stop at your breakpoint.
Use the vscode debugging controls thereafter.
Try to rebuild your launch.json file.
Remove the old file from the .vscode directory in vscode, then goto Run and Debug window and create a new launch file.

Debug mode does not activate breakpoint

I am trying to use debug mode in my react native application with visual studio code. I am using the command npx react-native run-android. It is activating the react native debugger, but it is not reaching any breakpoint in my application.
I did not find any tutorials to activate debug with npx, so could you guys show me one or explain me what is happening wrongly in this setup?
this is my launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug React Native",
"program": "${workspaceRoot}/.vscode/launchReactNative.js",
"type": "reactnative",
"request": "launch",
"platform": "android",
"sourceMaps": true,
"outDir": "${workspaceRoot}/.vscode/.react"
},
]
}
An interesting thing it is happening is once it is running the application if I click on the start debugging button my application restarts and it shows a message on debug console:
Launched debug configuration contains 'program' property which is deprecated and will be removed soon. Please replace it with: "cwd": "${workspaceFolder}"
Could not debug. The "path" argument must be of type string. Received type undefined
Since I have not received any answer, I took 3 days to discovered what was happening.
this is the correct configuration:
{
"version": "0.2.0",
"configurations": [
{
"name": "Attach to packager",
//"program": "${workspaceRoot}/.vscode/launchReactNative.js",
"type": "reactnative",
"request": "attach",
"sourceMaps": true,
"cwd": "${workspaceFolder}",
//"outDir": "${workspaceRoot}/.vscode/.react"
},
]
}
Must run the command npx react-native run-android
Once the android emulator is running batch job must be stopped in the terminal
Go to the debug tab in vs code and run the application
ctrl + m on android emulator
click on debug option
Those were the baby steps that I did in order to have the application run in debug mode.

Visual Studio Code errors when debugging Rust with "Missing auto-load debug_gdb_scripts"

I installed flatpak Visual Studio Code on Linux Mint. I'm trying to debug the "Hello world app" from the Rust book in VS Code.
src/main.rs:
fn main() {
println!("Hello, world!");
}
launch.json:
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug program",
"type": "gdb",
"request": "launch",
"target": "../target/debug/hello",
"cwd": "${workspaceRoot}"
}
]
}
When I cargo build the program and try to debug it, I get this error in Debug console:
warning: Missing auto-load script at offset 0 in section .debug_gdb_scripts
of file /home/gorn/nextcloud/viptrader/rust/target/debug/hello.
Use `info auto-load python-scripts [REGEXP]' to list them.
Running executable
warning: Error disabling address space randomization: Operation not permitted
I have installed these extensions:
rust-lang.rust
webfreak.debug
The real problem is the Error disabling address space randomization: Operation not permitted. The Missing auto-load script warning you can usually ignore.
The problem is likely caused by virtualization.
Try adding set disable-randomization off into the .gdbinit.
