auth token expired mid-vault-rotation for the secrets agent: auth error

TL;DR

Rotations longer than the token TTL die mid-run. Renew the token on a schedule inside its TTL, and on auth failures, re-authenticate and resume from the last completed step.

Error

auth token expired mid-vault-rotation for the secrets agent: auth error

Steps

1. Confirm expiry: the token worked at start and fails later with auth errors. Expected: expiry proven.
2. Add renewal at a fraction of the TTL during long runs. Expected: the token stays alive.
3. On 403 mid-run, re-authenticate, then reconcile state before continuing. Expected: clean resume.
4. Make rotation steps idempotent so resume is safe. Expected: no double-apply.
5. Size token TTLs to the longest expected rotation. Expected: margin.

When to use

• Vault rotations dying on token expiry.
• Long-running authenticated agents.

When not to use

• Permission errors (policy issue).
• Tokens invalid from the start (fix auth).

Tool compatibility

• Vault token TTLs and renewal; agent rotation loops.

Variant phrasings

vault token expired mid rotation

Renew and resume.

auth failed halfway through rotation

Re-auth, reconcile.

Why it happens

Tokens are time-bound; rotations are not. Any rotation longer than the TTL hits the boundary.

Edge cases

• Renewal itself needs permission; check the token can renew itself.
• Max TTL caps renewal; some rotations need fresh tokens, not renewals.
• Resume must verify state; blind continuation risks gaps.
