The error is obviously coming from the adafruit lib, so why are you reporting it here?

I don't use their libs, but I think they fixed it in their repo, and haven't released, so try their latest git.

Closing as off topic.

this isnt a forum for adafruit code issues. close this “issue” as it’s irrelevant here
