SQLAlchemy error NoModuleFound

So i had reboot my server and my program stopped and when i check it on my tmux that was already cleared, so i need to setup it again. The problem is i dont know my database URL so i just try to remember and try to connect on my beekeper with manual URL Hopefully i remember the username and the password so it can connect. Another problem when i try to change .env.example file with my database url and try to run the program. Apparently the program error so i install all requirements first with pip install -r requirements.txt

After that i try again, and still error. The error sounds like this, SQLAlchmey Error NoModuleFound ... dialect.... postgres.

I have check my url and username password and the database it is all correct. I try to reinstall the sqlalchemy and it is already installed and still cant run the program. So i ask the Chatgpt, apparently the problem is in the scheme

i use this

postgres://postgres:(password)@host:5432/database_name

the correct one is

postgresql://postgres:(password)@host:5432/database_name

the scheme must be postgresql not postgres.

So now it runs normally.
