radoslav-orlov reported every imported album landing in the soulsync
standalone library as "Unknown Artist" + the raw 10-digit album id
as the title + 0 tracks. Audit traced it to the click handler in the
import page dropping the source-of-the-album_id on its way to the
backend match endpoint.
Root cause:
`importPageSelectAlbum(albumId)` (the onclick on every suggestion /
search-result card) only passed the album_id string. The full search
response carried `source`, `name`, and `artist` per row — the
backend's `get_artist_album_tracks` needs source so it can route the
lookup to the metadata source the id actually came from. Without it,
the source chain tries each source's `get_album(id)` against an id
shaped for a different source — a Deezer numeric id against
Spotify's id format returns 404, against iTunes's collectionId range
returns 404, etc. — and falls through to the failure-fallback dict
in `get_artist_album_tracks`:
{
'success': False,
'album': {'name': album_name or album_id, 'total_tracks': 0,
'release_date': '', ...}, # no artist field at all
'tracks': [],
}
That broken album dict then flowed through `build_album_import_context`
→ post-processing pipeline → `record_soulsync_library_entry`, writing
"Unknown Artist" + album_id-as-title + 0 tracks rows into the
soulsync standalone library tables.
Why hybrid users hit it most: a Spotify-primary user searching for an
album → search returns the Spotify result PLUS Deezer fallbacks
(via `_search_albums_for_source`'s priority chain). Clicking a Deezer
fallback row then sent only the Deezer id to /album/match without
flagging that source — Spotify-first chain failed against the Deezer
id and the broken fallback got written.
Fix:
Frontend (`webui/static/stats-automations.js`):
- New `importPageState._albumLookup: { albumId: { id, name, artist,
source } }` populated by both card renderers (`_renderSuggestionCard`
+ the search-results render block) before they emit the onclick.
- `importPageSelectAlbum` reads source / name / artist from that
cache and includes them in the match POST body, so the backend
routes to the correct provider's `get_album` on the very first try.
- `_escAttr` applied to album_id in the onclick (defensive — ids
shouldn't contain quotes but `_escAttr` was already being used on
every other field interpolated into onclick attributes).
Backend (`web_server.py:import_album_match`):
- Defensive log warning when source is missing from the request body.
Catches any future regression where another caller (curl /
third-party / new UI flow) drops source again — it'll show up as
a visible warning in app.log instead of silently corrupting the
library.
Verification:
- Full pytest suite: 2264 passed, 1 skipped, 0 failed
- Ruff clean
- JS syntax clean
- Manual repro requires a real user flow (search albums on the
import page → click one → import) which isn't covered by the
existing unit tests; reviewer should verify against issue #524's
steps before merge.
