Getting a typeError error in django project

I created a virtual environment for my new project, installed django and started the new project. However, whenever i run a line of code with manage.py i get this long error.

PS D:\My stuff\Website development\Isow website\isow> python manage.py makemigrations
No changes detected

Database Entry:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

It does seem NAME is being converted to pathlib.Path (WindowsPath) object instead of string which then cannot be used in Django in same way as os.path expects strings (Not 100% sure as did not investigate in depth)

So casting in string would be appropriate

'NAME': str(os.path.join(BASE_DIR, "db.sqlite3"))
