Hello,  
I created sub app “slowa” in my app “angielski” then I added path to the INSTALLED\_APPS and when I run server I get the following error:

Traceback (most recent call last):  
File “C:\Users\krysz\AppData\Local\Programs\Python\Python310\lib\site-packages\django\apps\config.py”, line 245, in create

During handling of the above exception, another exception occurred:

Here’s my settings.py file:

```auto
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'angielski.apps.AngielskiConfig',
    'angielski.slowa.apps.SlowaConfig',
]

```

slowa/apps.py:

```auto
from django.apps import AppConfig
class SlowaConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'slowa'

```

I’ve also tried add ‘slowa’ or ‘slowa.apps.SlowaConfig’ instead of a ‘angielski.slowa.apps.SlowaConfig’, but it still doesn’t work.

I believe the name in slowa/apps.py should be ‘angielski.slowa’ and not just ‘slowa’.
