Could not find playlist data. Error code: "{error_code}"

Error message

Could not find playlist data. Error code: "{error_code}"

What it means

Raised by BandlabPlaylistIE._real_extract (yt_dlp/extractor/bandlab.py:418) when both candidate endpoints ('albums', 'collections', tried with expected_status=404 and fatal=False) returned a payload containing an errorCode. The last errorCode is echoed in the message; it means Bandlab's API refused the id for the requested playlist kind.

Solutions

1. Open the playlist URL in a browser while logged out and confirm it is publicly accessible
2. Copy the URL again from the address bar - the id must be the full hex/uuid string
3. Update yt-dlp (yt-dlp -U)
4. Report the URL and the errorCode value at https://github.com/yt-dlp/yt-dlp/issues with -v output

import urllib.request

def playlist_is_public(url):
    req = urllib.request.Request(url, headers={'User-Agent': 'Mozilla/5.0'})
    try:
        urllib.request.urlopen(req)
        return True
    except urllib.error.HTTPError:
        return False  # 404/private -> expect 'Could not find playlist data'

from yt_dlp.utils import ExtractorError

try:
    info = ydl.extract_info(url, download=False)
except ExtractorError as e:
    if 'Could not find playlist data' in str(e):
        mark_not_found(url)  # deleted/private/wrong id; retrying will not help
    else:
        raise

When it happens

Trigger: The id from the URL is not a public album or collection on Bandlab - deleted, private/unlisted, region-locked, or simply wrong (the regex expects a hex/uuid id); both endpoint probes 404 with an errorCode body.

Common situations: Deleted or private albums/collections; embed URLs whose query id was truncated; sharing links to drafts; API changes renaming endpoints or error envelopes.
