Hello, I'm looking into replicating and solving this, thanks for reporting.

This problem has been solved, thanks again for reporting this issue.
The Curseforge and Modrinth pages should be updated soon, give them an hour or two to get approval and upload, thanks!

An immediate version has been uploaded to the Releases section, you can grab the jar from there if you'd like.
See PR: #6
