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/upload and use the new asset_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).
