No audio URL found for the selected track.

Error message

No audio URL found for the selected track.

What it means

Raised by PixabayTool._download when the track dict selected for download has no 'audio_url' key. Tracks are harvested by scraping Pixabay search pages, so the URL depends entirely on the page's current HTML/DOM structure. If Pixabay changes markup or the scraper's regex misses, tracks enter the list with audio_url=None and download is impossible.

Solutions

1. Re-run the search step so track metadata is freshly scraped, then pick a track whose audio_url is populated.
2. Log or inspect the scraped track list (titles like 'Unknown' and missing durations are tell-tale signs the scraper broke) and choose another entry.
3. If all entries lack audio_url, the Pixabay page structure changed: update the extraction logic in the _search method to the new markup.
4. Fall back to a different music provider tool (e.g. suno_music or the HeyGen audio library) until the scraper is fixed.

Example fix

// before
track = tracks[inputs["track_index"]]
path = tool._download(track, inputs)  # RuntimeError: no audio_url

// after
track = tracks[inputs["track_index"]]
if not track.get("audio_url"):
    tracks = [t for t in tracks if t.get("audio_url")]
    if not tracks:
        raise RuntimeError("Pixabay scraper returned no playable tracks; page layout likely changed")
    track = tracks[0]
path = tool._download(track, inputs)

track = tracks[selection]
if not track.get("audio_url"):
    playable = [i for i, t in enumerate(tracks) if t.get("audio_url")]
    if not playable:
        raise RuntimeError("Pixabay scraper returned no playable tracks")
    selection = playable[0]
    track = tracks[selection]

def has_audio_url(track: dict) -> bool:
    url = track.get("audio_url")
    return isinstance(url, str) and url.startswith(("http", "//", "/"))

try:
    path = tool._download(track, inputs)
except RuntimeError as e:
    if "No audio URL" in str(e):
        # re-search and pick a track with a populated audio_url
        raise

When it happens

Trigger: Calling the pixabay_music tool with a track index/selection whose scraped entry lacked a parseable audio URL; Pixabay serving a different HTML layout (A/B test, redesign, bot detection page) so the extraction in _search returns {'title': 'Unknown', 'audio_url': None} entries.

Common situations: Pixabay site redesign or CDN/anti-bot interstitial breaking the scraper; selecting a track from a stale cached result list; running the tool in a region where Pixabay serves different markup.
