[Solved] An Unexpected Error Occured

[NullDev]

I created an entity, and when I try to summon it I just get "An unexpected error occurred trying to execute that command" with no stack trace or anything. Why is this happening? My code:

The Entity Class Itself:

Use the debugger to find the issue.

I ran it in debug mode in intellij but the console still says nothing but "An unexpected error occurred trying to execute that command"

Well, you have to put a breakpoint at the place where that error occurs and see why.

I have done that, and stepped through it, but I cannot figure out how to understand most of what it says. I updated the github w/ the MDK's .gitignore.

You need to register the attributes for your entity using EntityAttributeCreationEvent.

I have this in my EntityRegisterEvents class:

@SubscribeEvent
public static void registerEntityAttributes(EntityAttributeCreationEvent e) {
	e.put(HAY_HORSE, AttributeModifierMap.createMutableAttribute().createMutableAttribute(Attributes.MAX_HEALTH, 25)
		.createMutableAttribute(Attributes.FOLLOW_RANGE, 16.0)
		.createMutableAttribute(Attributes.ARMOR)
		.create());
}

Is something missing from it?

Yes, there was. I forgot a few attributes, namely Attributes.MOVEMENT_SPEED and Attributes.HORSE_JUMP_STRENGTH. Thank you for you help!
