THEN Initialize the SqliteSaver with a direct sqlite3 connection instead of using the from_conn_string() method. For example, create a connection with sqlite3.connect(':memory:', check_same_thread=False) and pass it to SqliteSaver(conn). Alternatively, use the context manager from_conn_string() within a 'with' block.

import sqlite3
from langgraph.checkpoint.sqlite import SqliteSaver

conn = sqlite3.connect(':memory:', check_same_thread=False)
memory = SqliteSaver(conn)
agent_executor = create_react_agent(model, tools, checkpointer=memory)
