minecraft version 1.16.5
forge 36.1.4

when included in a modpack for a server, attempting to connect to the server produces the error "internal exception: io.netty.handler.codec.encoderexception: java.lang.nullpointerexception"

Steps to Reproduce
run a forge server with this as one of the mods and attempt to connect

Could you please provide both a server and a client log?

Well I don't see anything that would suggest my mod as the culprit at the moment.
Can you connect without my mod in the mod list?
Or even just a vanilla server?

I got two server and client logs each and idk if you want debug or the dated one

client:
2021-05-29-1.log.gz
debug-1.log.gz

server:
2021-05-30-1.log.gz
debug-1.log.gz

I couldn't test this in the last 2 days.
I just tested it and I can see that there is an issue.
I will try to find the source for that and fix it as soon as I can.

You don't have to, I have already found the class responsible although atm I don't know what exactly is causing the error

thanks for testing it, sorry I've been scatterbrained and couldn't check this page.
I can also try a local test for you and get back to you later, if i remember
