Me and my friend are trying to join our other friends modded world through essential. Both of us keep getting an error saying:

Internal Exception: java.lang.NullPointerException: Cannot invoke "java.util.function.Function.apply(Object)" because the return value of "java.util.Map.get(Object)" is null.

Both of us receive this message when we join. My latest log reads

We have no clue what to do. Please help.

Essentials completely reworks the networking of minecraft.

You need to ask them.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.
