auth token expired mid-ClearML artifact download error agent failed to resume

TL;DR

Resume the download with the refreshed credential and byte ranges: the credential expired during a ClearML artifact download, so refresh it, then resume the transfer from the stored partial file instead of restarting or abandoning the artifact. Large artifacts outlive credentials routinely. A download path with no resume turns every expiry into a full restart, and agents under time limits abandon transfers that were nearly done.

Use this when

• The check or run fails with this symptom: a credential expires mid ClearML artifact download and the agent fails to resume.
• You are working on an agent workflow downloading ClearML model artifacts for comparison or deployment 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

• An artifact that was replaced since the download started, where resuming would splice two versions and a fresh download is required.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Confirm the partial file size and the artifact total size and digest from the task. Verify: the resume point and the expected final digest are known
2. Refresh the credential through the configured provider. Verify: the client authenticates again
3. Resume the download from the partial file using a range request or the storage client resume support. Verify: the transfer continues from the stored offset
4. Verify the completed file against the recorded digest. Verify: the digest matches, proving a clean splice
5. Add expiry aware refresh to the download step for artifacts over an agreed size. Verify: future downloads refresh before expiry

Compatibility: ClearML artifact downloads, resumable transfers, expiring credentials in agent workflows

Why it happens

Artifact downloads are the longest single operation in many agent workflows, and they start with whatever credential lifetime remains. Expiry mid transfer is a when, not an if, and only a resume capable path with a final digest check makes it a pause instead of a failure.

Edge cases / pitfalls

• Never trust a resumed file without the digest check; a changed artifact resumes into a corrupt hybrid.
• Store partial downloads outside temp locations that cleaners reap between attempts.
