source_asset_unavailable
Plugin API error source_asset_unavailable — referenced asset cannot be fetched.
HTTP 422 · not retryable
A source asset referenced by the job (via asset_id or an external URL in external_metadata) could not be downloaded by the worker, or the upload's signed URL has expired before the bytes were PUT.
How to fix
- Re-upload the asset via
POST /assets/uploadand use the newasset_id. - For pre-signed uploads, complete the PUT within the 15-minute TTL.
- If you supplied an external URL, confirm it is reachable from public networks (no VPN, no auth wall).
