Ошибка timed out waiting for launcher to connect

I did python debugging in VS code.
The following is the launch.json file:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387

            "request": "launch",
            "stopOnEntry": false,

            ],
            "console": "integratedTerminal"
        }
    ]
}

The following is settings.json file:

{
    "python.pythonPath": "c:\Users\susan\Documents\PythonScripts\venv\Scripts\python.exe",
    // to fix 'Timeout waiting for debugger connections'
    "python.terminal.activateEnvironment" : false
}

When I debug the python script in VS code, I got Time out waiting for launcher to connect and cannot debug the python script.

May I know how can I solve this issue?

Issue Type: Bug

Behaviour

Hi, I use the VS Code as my daily IDE. Usually my project is on a remote centos server, and it’s a web project in a docker container. And I develop the project in a remote mode by extension «Remote — SSH» extension, and debug by «Docker» extension (version: v1.22.1) and «Python» extension (version: v2022.10.0).

Recently I found that I’m not able to debug my project as VS Code told my «Timed out waiting for launcher to connect», like the image below:
image

but when I just switch to VS Code(v1.64.2)(python extension version is v2022.4.0), this error disappears and I’m able to debug, so I guess there should be a bug or a settings about the connect time.

After testing, I found that when the VS Code version is v1.69.1, but the python extension version is v2022.4.0, I’m able to debug, but when the python version is v2022.4.1, this error will alert and I can’t debug

Expected vs. Actual

Expected

Able to debug the project

Actual

Timed out waiting for launcher to connect

Steps to reproduce:

It’s hard to prepare such a project for you to reproduce it, is there any other things I can do to provide you?

this is my launch.json and tasks.json settings:

I did python debugging in VS code.
The following is the launch.json file:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.

            ],
            "console": "integratedTerminal"
        }
    ]
}

The following is settings.json file:

{
    "python.pythonPath": "c:\Users\susan\Documents\PythonScripts\venv\Scripts\python.exe",
    // to fix 'Timeout waiting for debugger connections'
    "python.terminal.activateEnvironment" : false
}

When I debug the python script in VS code, I got Time out waiting for launcher to connect and cannot debug the python script.

May I know how can I solve this issue?

>Solution :

Its very simple. Open the launch.json file and add the following into it:

{
  "name": "Python: Debug Console",
  "type": "python",
  "request": "launch",
  "program": "${file}",
  "console": "internalConsole"
}

Then save and exit it. Whatever you do, DO NOT clear the text already in there or else it may make it worser

        }
    ]
}

Could someone please help with this?
Not sure why i am getting this error.
I ran the code in an online python compiler where it worked fine.
So i can say that there is no error in the code.
Still not sure why the pop up is showing up suddenly.

All help are greatly appreciated!!

Когда я отлаживаю скрипт Python в коде VS, я получаю Time out waiting for launcher to connect и не могу отлаживать скрипт Python.

Могу ли я узнать, как я могу решить эту проблему?

Это очень просто. Откройте файл launch.json и добавьте в него следующее:

{
  "name": "Python: Debug Console",
  "type": "python",
  "request": "launch",
  "program": "${file}",
  "console": "internalConsole"
}

Затем сохраните и выйдите из него. Что бы вы ни делали, НЕ очищайте текст, который уже есть, иначе это может сделать его хуже.
