I'm running a 1.19.4 Fabric server and whenever I use a version of Travelers Backpack newer than 8.4.0. It says that there was an internal server error.

Here's a list of the mods I have installed.

• Cardinal Components API 5.1.0
• Cloth Config 10.1.105
• Fabric API 0.76.0
• Falling Tree 3.12.0
• Plasmo Voice 2.0.8
• Travelers Backpack 8.4.0 (Can't use a newer version or else it won't let anyone join)
• Trinkets 3.6.0

maybe update the mod on server?
