That’s strange. ViaVersion is not being used at all. See:

@doncullen It’s not a problem with existing villagers, but new villagers. Here’s a breakdown of the error trace:

A player spawns. They need to know what the world around them is like.
Minecraft loads several chunks near the player (chunks are 16x16 vertical sections of the world, used so that Minecraft doesn’t have to create the whole world at one time).
The chunk doesn’t yet exist, so Minecraft creates it.
The new chunk just so happens to contain a village which needs to be created.
Of course, the village needs villagers, so the game creates some villagers.
The villager tries to create some initial trades.
Now Sponge takes control and adds some trade offers to the villager.
Something (unknown to me) happens when setting up a trade including either enchanted items or enchanted books.
The server crashes, disconnecting the player.
The player gets upset.
