What I did ...
It seemed like the table for roles hadnt been created...and I saw that in the testing they created some data by using

db.create_all()

so in manage.py, I added db.create:
@manager.command
def deploy():
"""Run deployment tasks."""
from flask_migrate import upgrade
from app.models import Role, User
db.create_all()

Now seems to be ok....
