Error on Psychedelicraft when joining server

[thedeskinator]

Hey, I get an error that says "failed to encode custom packet fabworks sychronize" whenever I try to join my server. The dev of psychedelicraft told me to make a report here. I am using fabric. My mods list is Architectury, Artifacts, Carryon, Cloth-Config, Collective, Cupboard, Fabric API, psychidelicraft, Structure Essentials, Trinkets, and Simple voice chat, on 1.21.1. Serverside, it says

Does anyone know what could be causing this issue? Thanks

[Sollace]

Thanks for the report!

Can you try adding this version to your mods folder on the server and see if it fixes your problem?

https://github.com/MineLittlePony/Fabwork/releases/tag/1.3.1-beta.1%2B1.21

[thedeskinator]

Hey, thanks for responding
It gives me a different error now, even when I remove all mods except for the fabwork version you gave me, fabric api, and psychedelicraft
It says: failed to encode packet clientbound/minecraft:custom payload (Psychedelicraft update drug properties)
Serverside it just has the same message as what it says on the client

[Sollace]

Okay cool. It does at least sound like the first issue is resolved. I'll look into fixing the other one later tomorrow.

Thanks for your patience with this.

[thedeskinator]

no problem, thanks for the help

[SamBrimhall]

Adding that I'm experiencing the same issue posted above.

Here are my logs when trying to join the server after installing the suggested fix:

no problem, thanks for the help

Hey sorry for the wait. Here's another version that you can try. Hopefully this fixes all the issues.
If it works I will do a new release for both 1.21 and 1.20.5 (as I believe that version is affected)
