vscode-python extension - "python.envFile"/"envFile" parameters doesn't wor-CodePudding

I'm trying to configure a FastAPI based Python project to consume an .env (enviroment variables) file from an alternate location.

I've tried every possible configuration so that VSCode (vscode-python extension) loads the .env file from a specific location. Nothing works. I believe this is a bug of the vscode-python extension.

Any ideas on how I can resolve this (a workaround is also acceptable)?

settings.json (Workspace and User)

{
    [...]
    "python.envFile": "${workspaceFolder}/.env-DEV"
    [...]
}

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            [...]
            "envFile": "${workspaceFolder}/.env-DEV",
            [...]
        }
    ]
}

NOTE: In the

File structure

pyenv
├─ .env
└─ Test.py

Sample code

from dotenv import load_dotenv
import os
load_dotenv()
print(os.environ.get("envvar"))

Operation result

Note: If the env file name is not .env. Then you need to specify the file path in the code.

EDIT

launch.json configuration available in debug case
