agent's session expired mid-export and it kept querying unauthenticated: auth error

TL;DR

The session expired and the agent kept firing queries that all failed with 401, wasting time and log space. Check the response status on every batch; on 401, stop querying, re-authenticate, and resume. An unauthenticated loop is pure waste.

Error

Auth error: thousands of 401 responses logged; the export made no progress after the session expired.

Steps

1. Add a status check on every batch response. Expected: 401s are caught immediately.
2. On 401, halt the query loop at once; do not finish the batch plan unauthenticated. Expected: the waste stops.
3. Re-authenticate and verify with a cheap call. Expected: a confirmed-good session.
4. Resume the export from the last successful page. Expected: no gaps, no repeats.
5. Add a circuit breaker: N consecutive 401s halt the run even if the check is missed. Expected: defense in depth.

When to use

• Exports log masses of 401s.
• An agent ignores auth failures and continues.
• After session timeout changes.

When not to use

• Single 401s handled correctly (that is the good path).
• 403s (permissions, different handling).

Tool compatibility

• Any session-based API client.
• Agent loop guards.

Variant phrasings

querying unauthenticated

Halt on 401; re-auth; resume.

401 storm in logs

The loop never checked auth.

Why it happens

Query loops often check errors only at the end. Auth expiry mid-loop then produces thousands of failed calls before anyone notices.

Edge cases

• Distinguish 401 (re-auth) from 403 (stop and escalate); the handling differs.
• Resume needs the last good page persisted; without it you restart.
• Proactive refresh before long exports avoids the whole class.
