You need to talk to whoever you bought the server from. Forge doesn't sell servers.

The repository is private.

Have you registered the DeferredRegister with the mod event bus? You can link your GitHub repo.

Forge fires RegisterEvent (which is used internally by DeferredRegister) for each registry in a specific order, so changing the registration order in your code won't help. I haven't actually been able to run my mod since 1.20.6 because I'm waiting on Item Capabilities, so I haven't encountered this error myself. It looks like you can't use your DataComponentType during Item registration, so you probably need to get/add it on demand with getOrDefault and set, instead of in registration.

I don't think there's any documentation on them yet, I mainly just looked at the Vanilla code when implementing mine. You can see a fairly simple example here: Registration: https://github.com/Choonster-Minecraft-Mods/TestMod3/blob/f3bea10d5f455fa0904056caafd8c844b6fd13ae/src/main/java/choonster/testmod3/init/ModDataComponents.java#L50-L58 Item Registration: https://github.com/Choonster-Minecraft-Mods/TestMod3/blob/f3bea10d5f455fa0904056caafd8c844b6fd13ae/src/main/java/choonster/testmod3/init/ModItems.java#L264-L266 Usage: https://github.com/Choonster-Minecraft-Mods/TestMod3/blob/f3bea10d5f455fa0904056caafd8c844b6fd13ae/src/main/java/choonster/testmod3/world/item/EntityCheckerItem.java

The situation is the same in 1.20.6. Data Components were introduced in 1.20.5/1.20.6 and Item Capabilities haven't been re-implemented since then.

Item Capabilities haven't been re-implemented in 1.21 yet, you can use Vanilla's Data Components system instead. See DataComponents and the related classes.
