After Updating LuckPerms from 4.3.731 to 5.0.37 My Deluxe chat was totally broken. (Nothings Works)

On each messages send in the server, there is a Error poping up in console

Could be an issue with the legacy-API extension.
Did you try re-downloading it to exclude any possible corruption of the jar?

Other than that would this be an issue that @lucko needs to look into.

Which is why I asked them to open this issue. As that seems to be a bug.
Might even be related to a recent commit.

Well i Started it with the extension first, I wasn't even able to join my server and all my Plugins was just spamming errors,
So i joined Discord, see that it needed the extensions, installed it,
All plugin was back to normal exept Deluxechat
So i don't think that might be because of a Corrumption otherwise my other plugins would have stopped working even with the extension

Should be fixed by LuckPerms/extension-legacy-api@97f30ce

Please try updating extension-legacy-api to the latest version. :)
