Error trying to create a database: sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) unable to open database file

Question

I'm trying to create a database using Flask and Sqlite3, I am not sure this error is about the file path, as you can see in my code I have tried out different ways to specify the path but none seems to work, my code looks like this

from flask import Flask, request, jsonify, make_response
from flask_sqlalchemy import SQLAlchemy
import uuid
from werkzeug.security import generate_password_hash, check_password_hash
import jwt
import datetime
from functools import wraps
import os



app = Flask(__name__)

app.config['SECRET_KEY'] = 'thisissecret'


basedir = os.path.abspath(os.path.dirname(__file__))
app.config['SQLALCHEMY_DATABASE_URI']="sqlite:////"+os.path.join(basedir, "app.db")

#file_path = os.path.abspath(os.getcwd())+"\app.db"
#app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///'+file_path

#'sqlite:///mnt/c/Projects/bucketlist.db' C:\Users\MOSES MATOVU\Desktop
#app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:////mnt/C/Users/MOSES MATOVU/Desktop/bucketlist/app.db'
db = SQLAlchemy(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    public_id = db.Column(db.String(50), unique=True)
    name = db.Column(db.String(50))
    password = db.Column(db.String(80))
    admin = db.Column(db.Boolean)

class Todo(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    text = db.Column(db.String(50))
    complete = db.Column(db.Boolean)
    user_id = db.Column(db.Integer)


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

when I run the script: db.create_all() I get the following error

sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) unable to open database file

Fulls Details on the above error below
