  File "/Users/muninn/crestal/intentkit/.venv/lib/python3.12/site-packages/langmem/reflection.py", line 15, in <module>
    from langgraph.constants import CONF, CONFIG_KEY_STORE
ImportError: cannot import name 'CONFIG_KEY_STORE' from 'langgraph.constants' (/Users/muninn/crestal/intentkit/.venv/lib/python3.12/site-packages/langgraph/constants.py)

AS PER MY RESEARCH:

CONFIG_KEY_STORE last existed in langgraph 0.2.32.
Removed in langgraph 0.3.0 and later versions.
langmem 0.0.24 or later requires langgraph >=0.3.23, which no longer includes CONFIG_KEY_STORE, leading to this error.
