AttributeError: 'IPDetectorWebCheck' object has no attribute 'names'

I am having problems keeping the ip addresses updated on one of my Raspberry Pi setups. Sometimes they do not even get updated at all, the easiest way for me is to trigger a reboot of the device, so that I am able to access it from the outside again. This usually works, but I noticed some errors in the logs. I am calling dyndnsc via dhcpd hooks, to react directly on any changes on my networking interfaces, but also via crontab as a fallback every 11th minute of every hour. I assume the errors occur because the interfaces have no IP at the time that I am calling dyndnsc, but even in that case the dyndns entry should be updated as well and set to no IP/delete the IP.

/etc/dyndnsc.ini:

[dyndnsc]
configs = myconf_ipv4, myconf_ipv6

[myconf_ipv4]
# this will update your ipv4 address to the address
# the detector dnswanip returns:
use_preset = nsupdate.info:ipv4
updater-url = https://ipv4.mynsupdateinfosetup.tld/nic/update
updater-hostname = myclient.mynsupdateinfosetup.tld
updater-userid = myclient.mynsupdateinfosetup.tld
updater-password = mypassword
detector = webcheck4
detector-url = http://ipv4.mynsupdateinfosetup.tld/myip
#detector-parser = plain

[myconf_ipv6]
# this will update your ipv6 address to the address
# the detector dnswanip returns:
use_preset = nsupdate.info:ipv6
updater-url = https://ipv6.mynsupdateinfosetup.tld/nic/update
updater-hostname = myclient.mynsupdateinfosetup.tld
updater-userid = myclient.mynsupdateinfosetup.tld
updater-password = mypassword
detector = socket
detector-family = INET6
#detector = webcheck6
#detector-url = http://ipv6.mynsupdateinfosetup.tld/myip
#detector-parser = plain

I used the webcheck6 detector before, but that yielded different errors, so I commented that and tried the socket detector. Logs are from that very config right there.

/etc/dhcp/dhclient-exit-hooks.d/dyndns:
