Hello everyone, I hope you are well.

I am trying to install Odoo on my local computer. Even though it looks simple in the videos, every time I do the installation I get some error, schema error, internal server error, with the database. However, most were happening when trying to create the database.

After that I was able to create the database, and log in to the application, but then it triggers an internal error directly in the Odoo source code, and I don't understand why.

Here I show the log error:

2024-12-09 21:58:05,807 5364 ERROR odoo_db odoo.http: Exception during request handling.

Traceback (most recent call last):
