What causes "no shared albums found" in AlistGo/alist?

Treat 50820 as an empty list rather than a hard failure in listing code

no shared albums found

Error message

no shared albums found

What it means

The Baidu Photo union API returned errno 50820, mapped in Request (drivers/baidu_photo/utils.go:48) to 'no shared albums found'. It means the endpoint was asked for shared-album data but the account (or the given invitation context) has no shared albums to return. It is a normal empty-state response surfaced as an error.

Solutions

Treat 50820 as an empty list rather than a hard failure in listing code
Refresh the album list (GetAllAlbum) and invalidate cached album IDs when it fires
Verify the share/invitation code is still valid before listing its files

Example fix

// before
files, err := d.GetAllAlbumFile(ctx, album, passwd)
if err != nil { return nil, err }

// after
files, err := d.GetAllAlbumFile(ctx, album, passwd)
if err != nil && strings.Contains(err.Error(), "no shared albums found") {
    return []model.Obj{}, nil // empty state, not a failure
}
if err != nil { return nil, err }

Defensive patterns

Strategy: fallback

Try / catch

files, err := d.GetAllAlbumFile(ctx, album, passwd)
if err != nil && strings.Contains(err.Error(), "no shared albums found") {
    return []model.Obj{}, nil // treat as empty, drop stale album cache
}
if err != nil {
    return nil, err
}

Prevention

Refresh the cached album list when this fires instead of retrying the same album_id
Validate share/invitation codes before adding album mounts
Distinguish empty-state (50820) from auth errors so UIs show the right message

When it happens

Trigger: Calling GetAllAlbumFile / GetAlbumDetail for a shared album that was deleted or left; listing the shared-album scope on a fresh account that never joined any share; using an album_id that no longer resolves.

Common situations: Stale cached album IDs after the owner deleted the share; testing a new account with no shares; retrying after leaving an album.
