Bug: Cannot join server with Carpet + Polymorph installed

[Harvle]

Hi,

When i use Carpet and Polymorph on a server and try to join with the client, i get the linked error on the server side. It only happens when Polymorph is installed, not anything else. I have a few carpet addons as well, unsure if these are related.

• carpet-extra
• EssentialAddons
• Minitweaks

I've put an issue on the polymorph repo about this as well (illusivesoulworks/polymorph#287), but as it's an error with the carpet:hello payload it seems this is where the error originates from.

I have a bunch of other unrelated mods as well which i've put in this gist, in case this is needed.

MC version: 1.21.1
Carpet version: 1.21.1-1.4.147+v240813
Carpet-extra version: 1.21-1.4.148
Polymorph version: 1.0.6+1.21.1
Fabric API version: 0.106.0
Fabric Loader version: 0.16.7
