I was struggling with this issue for over a year but found the problem in my case.

VSCode python debugger will only recognize either CRLF or LF at the end of lines but not both. The debugger will appear to skip lines (but they are still executed) when there is a mix of the two in the file. This was happening in my case because I was adding lines of code while inside a debugging session and when I saved the file with the debugger session still live the end of line characters were different than the default in the file.

To solve it I simply had to change the line feed setting on right side of the bottom blue bar in VSCode from CRLF to LF back to CRLF and save the file.

Setting "justMyCode": false makes it stop at breakpoint:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Debug Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "stopOnEntry": true,
            "justMyCode": false
        },
    ]
}

Compile the program using the -g tag along with g++/clang++.

It looks that there is an issue in vscode (Issue opened by on github [here][1]) . But for now, the workaround is to set the protocol in the configuration (launch.json) to "inspector". With this option, the breakpoints is now reached properly.

Also, change the "--debug=5858" in the "runtimeArgs" option to "--inspect=5858"

{
  "type": "node",
  "request": "launch",
  "name": "Launch server with Nodemon",
  "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/nodemon",
  "runtimeArgs": [
    "--inspect=5858"
  ],
  "program": "${workspaceRoot}/src/server.ts",
  "restart": true,
  "port": 5858,
  "protocol": "inspector",
  "console": "integratedTerminal",
  "internalConsoleOptions": "neverOpen",
  "outFiles": ["${workspaceRoot}/build/**/*.js"],
  "sourceMaps": true
},

Also, after that, if you have a flashing message error telling you:

Cannot connect to runtime process, timeout after 10000 ms - (reason: Cannot connect to the target: connect ECONNREFUSED 127.0.0.1:5858)

It means that your program is too short and that debugger has not enough time to break on your breakpoint. To resolve that, add a second runtime argument to option "runtimeArgs": "--debug-brk" and set too "stopOnEntry" option to true

The final configuration should looks like this:

{
  "type": "node",
  "request": "launch",
  "name": "Launch server with Nodemon",
  "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/nodemon",
  "runtimeArgs": [
    "--inspect=5858",
    "--debug-brk"
  ],
  "stopOnEntry": true,
  "program": "${workspaceRoot}/src/server.ts",
  "restart": true,
  "port": 5858,
  "protocol": "inspector",
  "console": "integratedTerminal",
  "internalConsoleOptions": "neverOpen",
  "outFiles": ["${workspaceRoot}/build/**/*.js"],
  "sourceMaps": true
}

It should break on the first line of your entry javascript file. Then you can press F5 and it will reach your own breakpoint.

If you don't want to press F5 each time you run your program, you can instead embed your main entry code inside a setTimeOut function with at least 1000 ms of timeout.

All these options will give enough of time to vscode to break on your breakpoints.

Try this configuration in your launch file:

{
    "name": "Attach to Process",
    "type": "node",
    "protocol": "inspector",
    "request": "attach",
    "stopOnEntry": false,
    "port": 5858,
    "localRoot": "${workspaceRoot}",
    "remoteRoot": "/somepath/myprojectroot",
    "sourceMaps": true
}

Make sure the remoteRoot is correct path, otherwise it won't know where to look for the source files.

I use this configuration and work only if I insert this two line

// "stopOnEntry": true
// "justMyCode": false

{
  "version": "0.2.0",
  "configurations": [
    {
        "name": "Python: Debug Current File",
        "type": "python",
        "request": "launch",
        "program": "${file}",
        "console": "integratedTerminal",
        "stopOnEntry": true,
        "justMyCode": false
    },
  ]
}
