In you urls.py of the mywebapp app, make sure you have:
urls.py
mywebapp
app_name = 'mywebapp'
urlpatterns = [
re_path(r'REGEX_HOME', YOUR_HOME_VIEW, name='home'),
# or if you're not using regex
# path('HOME_PATH', YOUR_HOME_VIEW, name='home'),
# for Django 1.11
# url(r'REGEX_HOME', YOUR_HOME_VIEW, name='home'),
]
Substitute REGEX_HOME and YOUR_HOME_VIEW with your own values.
REGEX_HOME
YOUR_HOME_VIEW

Make sure you have
app_name='home'in yourmywebapp/urls.py. If that doesn’t solve the problem, then you need to show yoururls.py.– Alasdair
