Here is a clip to explain: https://streamable.com/5xjofu

Basically, when I walk out of range, I get a NullPointerException at LookController#setLookAt when it's being called from MeleeAttackGoal#tick.

Here is the log: https://privatebin.net/?05d1c1f8826d8bb2#79SvshoEzUji3NxL2oqTR2fi3CVzq66JPfps4HV1xTDb

Here is the class of the entity in question:

package com.isensehostility.entity_testing.entities;

import net.minecraft.entity.*;
import net.minecraft.entity.ai.attributes.AttributeModifierMap;
import net.minecraft.entity.ai.attributes.Attributes;
import net.minecraft.entity.ai.goal.*;
import net.minecraft.entity.passive.AnimalEntity;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.world.World;
import net.minecraft.world.server.ServerWorld;

import javax.annotation.Nullable;

public class GobletEntity extends CreatureEntity {

    public GobletEntity(EntityType<? extends CreatureEntity> type, World worldIn) {
        super(type, worldIn);
    }

    @Override
    protected void registerGoals() {
        super.registerGoals();
        this.goalSelector.addGoal(0, new SwimGoal(this));
        this.goalSelector.addGoal(7, new WaterAvoidingRandomWalkingGoal(this, 1.0d));
        this.goalSelector.addGoal(2, new MeleeAttackGoal(this, 1.3D, true));
        this.goalSelector.addGoal(2, new NearestAttackableTargetGoal<>(this, PlayerEntity.class, true));
    }

    public static AttributeModifierMap.MutableAttribute setAttributes() {
        return MobEntity.createMobAttributes()
                .add(Attributes.MAX_HEALTH, 1.0D)
                .add(Attributes.MOVEMENT_SPEED, 0.25D)
                .add(Attributes.ATTACK_DAMAGE, 2.0D);
    }

}

I'm not sure what is causing the error, or how to fix it.

Any help is appreciated.

Well, you should definitely add the NearestAttackableTargetGoal to the targetSelector and not the goalSelector, but I am not sure that will fix problem.
