Error when deploying django app to heroku

Question

I am trying to push my app to heroku, but I am getting the following error:

Counting objects: 1907, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (1894/1894), done.

Any ideas? I have the Procfile, requirements.txt, and runtime.txt files

Procfile:

web: gunicorn myapp.wsgi --log-file -

runtime.txt:

python-3.6.5

requirements.txt:

dj-database-url==0.5.0
Django==2.1.5
django-bootstrap4==0.0.7
django-ckeditor==5.6.1
django-heroku==0.3.1
django-js-asset==1.1.0

django-summernote==0.8.11.4
gunicorn==19.9.0
Pillow==5.4.1
psycopg2==2.7.7
pytz==2018.9
whitenoise==4.1.2

Possible solution, Heroku likes UTF-8 but not UTF-8-BOM.

Windows likes to use UTF-8-BOM, even if you select UTF-8, unless you specify without BOM it might assume with BOM.

Try and save your .txt file encoded specifically in UTF-8 without BOM.

Had to change the runtime.txt to 3.6.7 instead of 3.6.5
