auth token expired mid-CVAT-sync failed with 401 error

Not specified by the original author.

TL;DR

Fix this in the annotation platform by acting on the exact message first: refresh or reissue the credential for the exact scope the failing call needs, store it in the run secret store, and retry one read call before resuming the full run. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

auth token expired mid-QA-run failed with 401 error

Use this when

• The operation in the annotation platform fails with this exact message: auth token expired mid-QA-run failed with 401 error.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the annotation platform, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: refresh or reissue the credential for the exact scope the failing call needs, store it in the run secret store, and retry one read call before resuming the full run. Verify: make one authenticated read and confirm a 200 response before restarting the workflow.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in the annotation platform so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in the annotation platform on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Long runs outlive short lived credentials; the first call after expiry fails and every queued call behind it fails the same way until the credential is renewed.

How to fix: auth token expired mid-QA-run failed with 401 error

The how-to phrasing for the same failure in the annotation platform. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

the annotation platform troubleshooting for this failure

The symptom-first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: the annotation platform at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.

Fix the translation agent auth credential expiring mid sync

TL;DR

The credential expires during long translation-memory syncs, so refresh it before it dies or rerun with a fresh one. Long jobs outlive short-lived credentials, and the sync fails halfway with auth errors. Check the credential lifetime, refresh proactively mid-run, or split the job under the lifetime.

The error

Translation agent: 401 mid translation-memory sync at 60 percent
credential issued with a 1-hour lifetime, job runs 3 hours

Fix it

Step 1: Confirm the expiry pattern

grep -n "401" logs/tm-sync.log | head -3

Expected: The 401s start at a consistent elapsed time.

Step 2: Check the credential lifetime

node -e "console.log('decode the credential expiry, compare against the job duration')"

Expected: You see the lifetime is shorter than the job.

Step 3: Add proactive refresh before expiry

node -e "console.log('pattern: refresh the credential at 80 percent of its lifetime, retry the failed chunk')"

Expected: The job outlives any single credential.

Step 4: Rerun the sync to completion

node scripts/tm-sync.js | tail -3

Expected: The sync finishes with no mid-run 401.

When to use this

• A translation agent gets 401s partway through a long sync
• Jobs outlive credential lifetimes

When NOT to use this

• The 401 is immediate, the credential was never valid
• The failure is not auth, check the error

Tool and version compatibility

• Short-lived API credentials, long batch jobs
• Proactive refresh patterns

Variant phrasings

no refresh mechanism available

Split the job into chunks under the lifetime, each chunk with a fresh credential.

expiry varies by environment

Read the lifetime from the credential itself, do not hardcode it.

Why it happens

Credentials are issued with lifetimes, and batch jobs are written without regard for them. When the job runs longer than the lifetime, the API starts rejecting calls mid-stream and the sync dies partially complete.

Edge cases

• Refresh needs its own error handling, a failed refresh should pause not spin
• Checkpoint progress so a rerun resumes instead of restarting
• Long-lived credentials avoid this but widen the blast radius, prefer refresh

Thread query: translation agent auth token expired mid translation memory sync and the job failed

TL;DR: The credential expires during long translation-memory syncs, so refresh it before it dies or rerun with a fresh one. Long jobs outlive short-lived credentials, and the sync fails halfway with auth errors. Check the credential lifetime, refresh proactively mid-run, or split the job under the lifetime.

TL;DR

Refresh before the sync, and make the sync retry once on expiry: the Comet offline sync failed on an expired credential, so re-authenticate at sync start, and if expiry still lands mid-sync, refresh and resume the remaining runs instead of abandoning the batch. Offline syncs run long after the runs they upload, often on a schedule nobody watches. Credential lifetime and sync timing are set by different people, so expiry during sync is a design case, not bad luck.

auth token expired mid-Comet offline sync error agent failed token refresh failure

Use this when

• The check or run fails with this symptom: a credential expires mid Comet offline sync and the agent fails to refresh it.
• You are working on an agent workflow syncing offline Comet experiments on a schedule and the failure repeats on the same data or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A revoked credential belonging to a departed user, which needs the sync moved to a service account rather than a refresh.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Check the sync log for the point where authentication failed. Verify: runs before that point synced, the rest are still queued
2. Re-authenticate the sync process with the current credential. Verify: a test API call succeeds
3. Resume the sync for the remaining queued runs only. Verify: the backlog uploads without duplicating the earlier runs
4. Verify the workspace now holds every run from the batch. Verify: run counts match the local queue
5. Add a pre-sync authentication check and one automatic refresh and retry on an expiry response. Verify: the next expiry resolves without intervention

Variant phrasings

auth token expired comet offline sync token refresh failure

The shorter phrasing focused on the named failure.

token expired mid comet sync agent error

The symptom phrasing a searcher tries next.

comet offline sync credential refresh fix

The variant naming the failing stage or tool directly.

Compatibility: Comet ML offline experiments and sync, agent scheduled sync workflows

Why it happens

Offline mode decouples logging from connectivity, and the sync job inherits credentials that were issued for interactive use. A long sync crosses the expiry boundary mid batch, and a sync written without a refresh path abandons the remaining runs silently.

Edge cases / pitfalls

• Track which runs synced before the failure; an all or nothing assumption causes duplicate uploads on the retry.
• Service accounts with rotation reminders are the durable fix for scheduled syncs.
