I do have a flask application running on port 8000 because i have logstash running on port 5000.
app.run(debug=True, host='0.0.0.0', port=8000)
i can run my app successfully. but when i use VScode debugger it throws
OSError: [Errno 98] Address already in use
because the debugger tries to run my app on port 5000.
i tried editing .vscode/launch.json and set "port": 8000 inside configurations but the error still the same. how can i tell the VScode to run my app with debugger on another port?
Add args key to your debug configuration and set the port there:
https://code.visualstudio.com/docs/python/debugging#_set-configuration-options
{
"name": "Python: startup.py",
"type": "python",
"request": "launch",
"program": "${workspaceFolder}/startup.py",
"args" : ["run", "--port", "8000"]
}
