Django no reverse match on heroku

I am getting NoReverseMatch at /post/1/ Reverse for 'blog_home' not found. 'blog_home' is not a valid view function or pattern name. this error on my Django website hosted on Heroku, but the code works fine when I host the website locally. I think that it has something to do with Heroku. My urls.py

urlpatterns = [
    path('', PostListView.as_view(), name='blog-home'),
    path('post/<int:pk>/', PostDetailView.as_view(), name='post-detail')
]

views.py: https://controlc.com/fd518ea0 (link because stack overflow said too much code)

Error:

Environment:


Request Method: GET
Request URL: http://<appname>.herokuapp.com/post/1/

Django Version: 2.2.1
Python Version: 3.9.0

In urls.py, blog-home is hyphenated. The failing code is attempting to reverse blog_home (with an underscore), which does not match. Change one or the other so they match.
