The uSkyBlock version v3.1.0-SNAPSHOT-518f3fa you are using is only compatible with 1.20.3 and newer, i.e., when minecraft:grass was renamed to minecraft:short_grass.

[BazZziliuS]

Too bad. Am I right in understanding that versions below 1.20.3 will no longer be supported?

[minoneer]

Is there a particular reason to stay on 1.20.1 instead of 1.20.3? Supporting more, especially older versions of the game, always has an overhead, so I'm trying to understand the benefits.
Ultimately it's @Muspah's call to make :)

I'm all in favor of moving forwards and dropping legacy support when possible, but if there's a good reason to support an older version, I don't mind. But please drop support when possible.

This version still includes many popular mods that are regularly updated, which is its main appeal.
I want to launch a server on this version, but this error prevents players from enjoying a seamless gaming experience, and it’s a significant concern for me.
If you could help me find a previous build where this error didn’t occur, I believe it would resolve my issue—especially if the latest version doesn’t include any critical fixes.

I see; I didn't think about moded servers.

Imho, it doesn't make sense for us to support versions before 1.20.5 going forward. Minecraft completely changed its item system in 1.20.5; therefore we would have to duplicate significant parts of the item specification logic - which is central to the plugin.

However, looking at the build history, we currently have no version compatible with 1.20, 1.20.1, and 1.20.2, since we directly updated to 1.20.3. I therefore forked the pre-1.20.5 version and adjusted it to compile with 1.20.1: https://github.com/uskyblock/uSkyBlock/tree/1.20.1.

The build is attached below. It is untested, so please proceed with caution and do your own testing. We won't officially support it, but it should be the same version as the one you are currently using (v3.1.0-SNAPSHOT-518f3fa). There are no known major issues - we mainly reworked the item system to the new component format and updated a bunch of stuff to be easier to maintain.

Let me know if that works for you.

Thank you very much, everything works.
