THEN Use SqliteSaver with a direct sqlite3 connection (e.g., `conn = sqlite3.connect(':memory:', check_same_thread=False)`; `memory = SqliteSaver(conn)`) or wrap the checkpointer creation within a context manager. Alternatively, switch to MemorySaver for in-memory checkpointing.

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)
