Summary

AI summary

Fixed Neo4j database selection causing AuthenticationError when using config dict.

Full changelog

v0.1.1 (2026-02-27)

Bug Fixes

  • Use NEO4J_DATABASE env var instead of config dict for non-default database (74e1188)

mem0ai's graph_memory.py passes config as positional args to Neo4jGraph() where pos 3 is token, not database. Setting database in the config dict causes it to land in the token parameter, resulting in AuthenticationError. Use NEO4J_DATABASE env var which langchain_neo4j reads via get_from_dict_or_env().

Upstream: mem0ai #3906, #3981, #4085 (none merged)

Resolves: PAR-57

Detailed Changes: v0.1.0...v0.1.1
