Show your code.

public class NimbatEntity extends BatEntity {
    public NimbatEntity(EntityType<? extends BatEntity> type, World worldIn) { super(type, worldIn); }

    public static AttributeModifierMap.MutableAttribute setCustomAttributes() {
        return MobEntity.func_233666_p_()
                .createMutableAttribute(Attributes.MAX_HEALTH, 1.0f);
    }

    @Override
    public boolean canBeLeashedTo(PlayerEntity player) { return true; }

    @Override
    public boolean canDespawn(double distanceToClosestPlayer) { return false; }
}

Bats do not use the normal AI system. The leashing code (updateLeashedState) is designed to work with the normal goal-based AI system. You'll have to override it and adapt it to the Bat's movement code.

Any guidence on how i can adapt the code?

Looking at the bat's movement code (updateAITasks) it seems it just picks a random position and fly straight there. You might get a reasonable result by making that pick the target of the leash if it is leashed instead of a random position.

Ill try and ask if anything goes wrong thank you!

Do i override the updateAiTasks or still stay on the leasedstate? Also i suppose i have to add an if statement checking if the bat is leased in the else?

else {
         if (this.spawnPosition != null && (!this.world.isAirBlock(this.spawnPosition) || this.spawnPosition.getY() < 1)) {
            this.spawnPosition = null;
         }

         if (this.spawnPosition == null || this.rand.nextInt(30) == 0 || this.spawnPosition.withinDistance(this.getPositionVec(), 2.0D)) {
            this.spawnPosition = new BlockPos(this.getPosX() + (double)this.rand.nextInt(7) - (double)this.rand.nextInt(7), this.getPosY() + (double)this.rand.nextInt(6) - 2.0D, this.getPosZ() + (double)this.rand.nextInt(7) - (double)this.rand.nextInt(7));
         }

         double d2 = (double)this.spawnPosition.getX() + 0.5D - this.getPosX();
         double d0 = (double)this.spawnPosition.getY() + 0.1D - this.getPosY();
         double d1 = (double)this.spawnPosition.getZ() + 0.5D - this.getPosZ();
         Vector3d vector3d = this.getMotion();
         Vector3d vector3d1 = vector3d.add((Math.signum(d2) * 0.5D - vector3d.x) * (double)0.1F, (Math.signum(d0) * (double)0.7F - vector3d.y) * (double)0.1F, (Math.signum(d1) * 0.5D - vector3d.z) * (double)0.1F);
         this.setMotion(vector3d1);
         float f = (float)(MathHelper.atan2(vector3d1.z, vector3d1.x) * (double)(180F / (float)Math.PI)) - 90.0F;
         float f1 = MathHelper.wrapDegrees(f - this.rotationYaw);
         this.moveForward = 0.5F;
         this.rotationYaw += f1;
         if (this.rand.nextInt(100) == 0 && this.world.getBlockState(blockpos1).isNormalCube(this.world, blockpos1)) {
            this.setIsBatHanging(true);
         }
      }

Here i mean. But also how do I take the lead position in the world?
