H10 error when trying to start heroku app

I am trying to start my heroku app with a python flask app, but I am getting the h10 error and the only thing I can see in the log is the Tkinter not found but I am not using Tkinter in this project please help. I've been searching on the web and on other stack overflow questions, but most just say to make sure you don't declare a port or some js server thing. I haven't found anything that helps and when I read the log all I see is the Tkinter but I tried to purge it from my code but it still tries to call it.

The immediate problem is caused by the following import:

from turtle import back

It doesn't make much sense to use the turtle module in a web application. Fortunately, you don't seem to actually be using it.

Remove that line, commit, and redeploy.

Once that's done, you will probably find that your SQLite database doesn't behave as you expect it to.

Heroku's ephemeral filesystem makes file-based databases like SQLite a poor choice. A client-server database like PostgreSQL will work much better. Heroku's own Postgres service might be a good place to start.
