ARTIFACT_UPLOAD_FAILED_ERROR

Error message

ARTIFACT_UPLOAD_FAILED_ERROR

What it means

CodeArtifactUploader.upload() posts an artifact file to the internal upload endpoint and strictly validates the result: HTTP status must be 2xx AND the JSON payload must be a dict with an integer code == 0 and a dict 'data'. Any deviation (non-2xx, redirect, non-JSON body, business error code, malformed payload) raises RuntimeError('artifact_upload_failed'). Callers (_upload_artifact) catch this and mark the artifact's upload_error field.

Solutions

1. Verify SKILL_SANDBOX_ARTIFACT_UPLOAD_URL is reachable and returns the expected {code:0, data:{...}} envelope (curl the endpoint).
2. Check SKILL_SANDBOX_ARTIFACT_UPLOAD_TOKEN (or *_FILE) is set and >= 32 characters; confirm it is accepted (no 401/403).
3. Confirm the file is under 20MB and total uploads under 100MB for the run; skip or split oversized artifacts.
4. Retry transient network failures; check server logs for the business error code returned in the payload.

Example fix

// before
payload = await response.json(content_type=None)
return payload  # crashes later or hides business errors
// after
if not 200 <= response.status < 300:
    logger.warning("artifact upload http status={}", response.status)
    raise RuntimeError(ARTIFACT_UPLOAD_FAILED_ERROR)
payload = await response.json(content_type=None)
if not (isinstance(payload, dict) and payload.get("code") == 0):
    raise RuntimeError(ARTIFACT_UPLOAD_FAILED_ERROR)
return payload["data"]

uploader = CodeArtifactUploader(sandbox_config)
if not uploader.is_configured():
    # skip artifact upload instead of failing the run
    return

def is_valid_upload_payload(p: object) -> bool:
    return (isinstance(p, dict) and isinstance(p.get("code"), int)
            and not isinstance(p.get("code"), bool) and p["code"] == 0
            and isinstance(p.get("data"), dict))

try:
    await uploader.upload(name, data, ctype)
except RuntimeError:
    artifact["upload_error"] = "artifact_upload_failed"  # degrade gracefully

When it happens

Trigger: Upload POST returns non-2xx status or redirects; response body is not JSON; payload.code != 0 or code is a bool/missing; payload.data is missing or not a dict; aiohttp network/timeout error during the 60s-limited request.

Common situations: Wrong SKILL_SANDBOX_ARTIFACT_UPLOAD_URL or service down; artifact upload token missing/shorter than 32 chars causing 401/403; file exceeds 20MB per-file or 100MB total limits rejected by server; transient network failure.
