I am also experiencing this on python 3.8 with create method.

user = User.query.filter_by(email=email).first()
        if user.validate(password):
            response_msg = {'jwt': create_jwt(identity=email)}
            status_code = 200

results in: "msg": "'str' object has no attribute 'decode'"
