Pyinstaller with fastapi and database

This is folder structure of my fastapi app. I am using sqlalchemy to connect to Postgres database. I am using uvicorn server.

In my main.py:

functions.models.Base.metadata.create_all(bind=engine)
tasks.models.Base.metadata.create_all(bind=engine)
app= FastAPI()
app.include_router(functions.main.router)
app.include_router(tasks.main.router)

if __name__ == "__main__":
    uvicorn.run(f"{Path(__file__).stem}:app", host='0.0.0.0', port=8127, workers=1)

I am trying to compile into exe with pyinstaller. This is my spec file, please advice what is wrong that main doesn't load:
