certbot-dns-pdns is broken on certbot-dns-lexicon 3.17.0

The API ostensibly changed, because now my challenges fail while the pDNS plugin is trying to use dns-lexicon:

Probably the same (or related) error: #9982

Thanks for reporting! Looks like a bug in certbot / dns-lexicon.
Also an odd one. I can't reproduce it in isolation (in a venv). So I'm assuming there may be some dependency versioning / pinning issue at play. I will need to investigate further.
