SpotipyFree crashes with KeyError: 'ownerV2' — Spotify changed their internal API response format and the library is out of date. curl_cffi presents a real Chrome TLS fingerprint so open.spotify.com/api/ server-time responds (plain Node.js TLS is filtered by Spotify's WAF). Node.js TOTP fallback always failed on this for the same reason — removed. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
