I have put the server-side mod in the latest version, with the server in 1.16.5 and it starts correctly, but when I enter the server it gives this error.
I don't know if it is my problem, if so what would be the solution?
The server-side mods are (all 1.16.5) :

• Blocklogger
• Carpet
• Carpet Extra
• Discord Fabric Whitelister
• Dynmap
• Fabric API
• Fabric Discord Link
• Fabric language kotlin
• FastFurnace
• Krypton
• Lazydfu
• Lithium
• MiniMOTD
• Phosphor
• TicTcas
• Watchtower
• and RandomPatches
