Bug Description

I'm running a Paper server on Aternos with the WorldEdit plugin installed. This used to work just fine, but now I'm suddenly getting an error, saying that my version of WorldEdit doesn't fully support the Bukkit API. I have re-installed everything from scratch, but I cannot get WorldEdit to work properly. My guess is that the Paper server received an update that bumped the Bukkit API to a new version? I notice that the date stamp in the Paper version says 2024-10-20. Any help figuring this out would be appreciated. The relevant log file says:
