Steps to Reproduce
The bug happens seemingly randomly on our server. The only way I could think to reproduce would be to be near (black) moas, either a pack of adult saddled or unhappy baby.
What You Expect To Happen
I expect to join a server other people are playing on.
What Actually Happened
I try to join a server, only to be left at a "Joining..." screen. When other people leave or try to join for the first time, they are stuck on loading too. Restarting server helps, until some (possibly unlogged) event happens that makes it impossible to join back into the game.
Additional Details
This bug doesn't seem to have any pattern at all. It just seems to happen after some time randomly. We have brought moas to overworld, we are incubating them there in caves and once they grow up, we bring them above the ground. The issues seem to have started after we brought them from the aether, however it may be due to something else that I don't see (because the log mentions black moa and nothing else).
I tried to kill them, restart the server and I'll comment back soon if anything changes.

Not sure why this is occurring yet, I'll have to get some thoughts from other devs. My assumption is this is a mod conflict since its basically saying this line of code is air which if the case means something is getting very broken somewhere.
Killing the mobs seems to have "resolved" the issue, however I have not tested it yet in Aether dimension itself.
Is this on a world that used to be on an older version than 1.21?
No, this is a fresh world created on 1.21.1.
Overworld and other dimensions (including The Aether) were pregenerated before other players joined. After one of the players reached the Aether and brought back the Moas, the issues started to happen.
I suspect it may be the babies, but I'm not sure. We killed all of the moas in the overworld and there were no similar issues since.
Affects Fabric 1.21.1; softlocked until restarting the server
java.lang.IllegalArgumentException: Failed to serialize ResourceKey[aether:moa_type / aether:blue]: Item must not be minecraft:air
It is seemingly related in that it has happened only after incubating a black moa, but unrelated in that suddenly it's blaming the blue moa type. I was in a completely different dimension from the tamed moa when the bug happened.
Honestly given the fact that it's blaming a resource key, and that it's returning air, I do wonder if the registry key got passed along as the wrong thing during the initial connect, causing the rather strange moa type is air bug.
Another person has said this might somehow also be a bug caused by version mismatches between the client and the server, since it stopped for them after they made sure everyone was on the same version but also still after some restarts and additional time weirdly.
