Exception in server tick loop | 1.17.1 Forge

Posted October 20, 20214 yr

Hi, I'm making my minecraft forge server on version 1.17.1.
Whenever I run the server I get this error, I have tried many ways and could not find the solution.

Description: Exception in server tick loop

java.lang.NullPointerException: Cannot invoke "com.google.gson.JsonArray.iterator()" because "â˜ƒ" is null

Forge 1.20.1 OpenAL 40963 and 40961 in DynamicSoundFilters

I copied the mod from Fabric to Forge, but errors 40963 and 40961 appear, I still don’t know the reason, I tried it in a single world, it doesn’t reproduce, the reason for the error is unknown, sometimes it exists and sometimes it doesn’t. andre111/dynamicsoundfilters: GitHub repository
The ported code to Forge is no different from the original, so you can use the source code for testing. The same error occurred on the Fabric build, mods that were on both builds:
Sodium
Create
I only know that the error occurs along the following path: MixinSoundSystem call onPlay -> FilterManager call updateSoundInstance

My friend keeps getting disconnected from our Forge Server

It is, but that is mainly to set up configs per player, I think. I don't believe it is messing chest inventories. I can try to remove that one tho and see if it fixes anything.
