Which launch config does the VS Code Python extension’s debug button use?

when I open a .py file in vscode, there’s a debug button shown up at the top-right coner of the vscode window.

enter image description here

I have a multi-root workspace, and one launch config defined. When I start debuging/running with F5 button, the one launch config is automatically selected, and everything works fine. But if I use the debug button at the top-right coner as high-lighted, vscode complains it cannot find the modules imported in the workspace.
What debug/run environment does this button use?

    You have to config a launch.json file.

    • At Run & Debug (left menu) enter image description here, you can set a config file:

    VS Code will try to automatically detect your debug environment, but if this fails, you will have to choose it manually:

    You can use IntelliSense suggestions (Ctrl+Space) to find out which attributes exist for a specific debugger. Do not assume that an attribute that is available for one debugger automatically works for other debuggers too.

    I’m pretty sure the Run Python File button invokes the same thing as the Python: Run Python File in Terminal command in the command palette, which- if I understand correctly- doesn’t use launch configs, and instead uses settings that start with python.terminal.*. The current list of those settings at the time of this writing is the following (shown with their default values):

    // Activate Python Environment in the current Terminal on load of the Extension.
"python.terminal.activateEnvInCurrentTerminal": false,

// Activate Python Environment in all Terminals created.
"python.terminal.activateEnvironment": true,

// When executing a file in the terminal, whether to use execute in the file's directory, instead of the current open folder.
"python.terminal.executeInFileDir": false,

// When launching a python terminal, whether to focus the cursor on the terminal.
"python.terminal.focusAfterLaunch": false,

// Python launch arguments to use when executing a file in the terminal.
"python.terminal.launchArgs": [],
