Data type mismatch when running database migrations

When running python manage.py makemigrations followed by python manage.py migrate, I get this error: django.db.utils.IntegrityError: datatype mismatch. I cloned a fresh copy and still get the error. This is the exact sequence I did if anyone wants to reproduce it. Anyone know why this is happening, or if it’s a problem just on my end?

git clone [e-mail]:phageParser/phageParser.git phageParsertest
cd phageParsertest/phageAPI
git checkout django-dev
python manage.py makemigrations
python manage.py migrate # this is where the error happens

This is the full error message:

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

@mbonsma I think the problem arises since the models file has been changed and not been migrated to the old database. I would suggest resetting the database first and then migrating. According to this, resetting can be done by running python manage.py flush

It works for me! but I have to runpython manage.py createsuperuser to create a superuser again.
