Reference asset {i} (Id={asset_id}) is not Active (Status={r

Error message

Reference asset {i} (Id={asset_id}) is not Active (Status={result.status}).{extra}

What it means

Seedance reference assets are uploaded out-of-band and polled via /proxy/seedance/assets/{id}. Only status 'Active' assets are usable; any other status (e.g. 'Failed', 'Pending', 'Error') raises, appending the API's error code/message when present.

Solutions

1. Re-upload the asset and use the fresh asset id.
2. Inspect the appended error code/message to see if moderation or format caused the non-Active status and fix the source file.
3. Blank/whitespace-only ids are skipped - make sure you did not paste a truncated id that maps to someone else's or a dead asset.

status = await get_asset_status(asset_id)
if status != 'Active':
    asset_id = await reupload_asset(source_file)  # fresh id

try:
    assets = await collect_active_assets(cls, asset_ids)
except ValueError as e:
    if 'not Active' in str(e):
        asset_ids = await reupload_all(sources)  # one retry with fresh uploads
        assets = await collect_active_assets(cls, asset_ids)
    else:
        raise

When it happens

Trigger: An asset_ids entry resolves to an asset whose GetAssetResponse.status != 'Active' - upload failed, moderation rejected it, or polling raced ahead of processing.

Common situations: Reusing stale asset ids from a previous session; content moderation rejected the upload; network hiccup during upload left the asset in a failed state.
