Hi Guys,
This is the error I am getting:
(first_django_app) ➜ first_django_app git:(master) heroku run python
manage.py loaddata books/fixtures.json
Running python manage.py loaddata books/fixtures.json on ⬢ gotbooksapp...

The above exception was the direct cause of the following exception:

I have done the following: rm -f db.sqlite3
run python manage.py makemigrations
run python manage.py migrate
I had to add all the information again as the database had been cleaned out
I then implement fixtures.json locally
I did a git add ., git commit -m and git push heroku master
I did run heroku run python manage.py migrate
I finally run python manage.py loaddata books/fixtures.json
I still have the same errors again
