Hi, everyone

I have this problem with few plugins past days.
I don't know what's wrong so I can't give you ways to reproduce the error, so I will just paste a console output here.

Hope someone had the same problem and could help me with it.

Console Output

Hi, please try updating ProtocolLib to v4.8.0 (latest release) and see if the issue persists

I managed to fix it minutes after posting a issue, sorry for opening a issue without reading other issues.

Version I used: https://ci.dmulloy2.net/job/ProtocolLib/lastSuccessfulBuild/
