[Python] vscode python extension does not read .env file in debug mode

I'm trying to run a Python code in a Docker container. I'm using the debug tool with the VScode Python extension.

I have a .env file in the same directory as Docker-Compose, but when I run the code in debug mode, the .env file is not read. If I access the container via the command line and run export, the environment variables are in the container. However, the Python code below does not print them:

import os
from dotenv import load_dotenv

if __name__ == "__main__":
load_dotenv(dotenv_path="/home/project/app/.env")
envVar=os.environ
print(envVar)


In docker-compose.yml I added the field:

env_file:
- .env


In launch.json I added:

"envFile": "${workspaceFolder}/.env",


In settings.json I added

"python.envFile": "${workspaceFolder}/.env",


And now I don't know what to do to get the environment variables read in the python code.
