If you have upgraded your .Net Core SDK recently, just update netcoreappX.X

 "program": "${workspaceFolder}/CommunityBot/bin/Debug/netcoreappX.X/CommunityBot.dll"

in launch.json file. Check your .Net Core SDK version by dotnet --version

If you're using a pytest-cov module you might also wanna have a look at pytest configuration settings note:

Note If you have the pytest-cov coverage module installed, VS Code doesn't stop at breakpoints while debugging because pytest-cov is using the same technique to access the source code being run. To prevent this behavior, include --no-cov in pytestArgs when debugging tests, for example by adding "env": {"PYTEST_ADDOPTS": "--no-cov"} to your debug configuration.

See an example configuration file (launch.json) below:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Tests",
            "type": "python",
            "request": "test",
            "console": "integratedTerminal",
            "justMyCode": false,
            "env": {"PYTEST_ADDOPTS": "--no-cov"}
        }
    ]
}

On the VSCode settings search for 'debug javascript use preview', and then disable it. It should now bound all breakpoints.

You could try to use the following codes in your launch.json:

{
    "name": "Python: Debug Tests",
    "type": "debugpy",
    "request": "launch",
    "program": "${file}",
    "purpose": [
        "debug-test"
    ],
    "console": "integratedTerminal",
    "justMyCode": true,
    "env": {
        "ON_HEROKU": "0",
        "PYTEST_ADDOPTS": "-c pytest-debug.ini",
        "ECHO_SQL_QUERIES": "1"
    },
}

pytest-debug.ini is a separate configuration file for debugging. This file should be similar to your pytest.ini file, but without the addopts line:

[pytest]
env = 
    TESTING=true
    ENV=local

This way, when you're debugging your tests, pytest will use the pytest-debug.ini configuration file.

You will need to change your setting "justMyCode" to false for breakpoints to work in vscode.
