It doesn't recognize my tables from SQL Lite, what am I doing wrong?

I am using langchain (API/ChatGPT) to tell my local database however when I pass the name of my table "clientes" it does not recognize me and I get this message:
OperationalError: (sqlite3.OperationalError) no such table: clientes [SQL: SELECT direccion FROM clientes WHERE nombre = "Luis" LIMIT 1;] (Background on this error at: https://sqlalche.me/e/20/e3q8)

Error from "front"

Database

Front Page

I have already tried to reference the "clientes" table but I am able to connect, what would it be like if I wanted to access all my 3 tables: "clientes", "personas" and "ventas"?

I am attaching screenshots and codes so that someone can help me, please..
