db.create_all() - не выполняется SQL Ubuntu

Question

Создал тестовую базу. Создал пользователя mysql со всеми правами для всех баз. Начал писать приложение, но не могу выполнить создание постов в этой базе данных, появляется странная ошибка. Перед самой ошибкой скажу такие факты: Приложение, для которой создается база - работает. Возможно проблема с версиями mysql и mysql-connector, однако устанавливал я всё последних версий. Недавно я уже делал это и такой проблемы не было, поэтому я и встал в тупик. Благодарен буду любой наводке.

Файл config.py

class Configuration(object):
    DEBUG = True
    SQLALCHEMY_TRACK_MODIFICATIONS = False
    SQLALCHEMY_DATABASE_URI = 'mysql+mysqlconnector://admin:admin@localhost/test1'

Файл app.py

from flask import Flask
from config import Configuration
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config.from_object(Configuration)

db = SQLAlchemy(app)

Файл models.py

from app import db
from datetime import datetime
import re

def slugify(s):
    pattern = r'[^\w+]'
    return re.sub(pattern, '-', s)

class Post(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(140))
    slug = db.Column(db.String(140), unique=True)
    body = db.Column(db.Text)
    created = db.Column(db.DateTime, default=datetime.now())

    def __init__(self, *args, **kwargs):
        super(Post, self).__init__(*args, **kwargs)
        self.generate_slug()

    def generate_slug(self):
        if self.title:
            self.slug = slugify(self.title)

    def __repr__(self):
        return '<Post id: {}, title: {}>'.format(self.id, self.title)

Файл main.py

from app import app 
from app import db
from posts.blueprint import posts
import view

app.register_blueprint(posts, url_prefix='/blog')

if __name__ == '__main__':
    app.run()

Остальные вроде не так важны файлы, но буду готов докинуть.

Команды, которые выполняю.

Захожу в виртуальную среду venv
В ней запускаю python, далее команды

import models

from app import db

db.create_all()

Но после крайней получаю ошибку длинной в жизнь:
