Solved BlockBreakEvent Exception

I don't know what's wrong but everytime I use the config to set the msg it does not work. I get a blockbreakevent exception.

Code:

      @EventHandler
      public void onBreakBlock(BlockBreakEvent e)
      {
        if (e.getBlock().getType().equals(Material.DIAMOND_ORE))
        {
          if (diamonds.contains(e.getBlock())) {
            return;
          }
          int i = getDiamondsAround(e.getBlock()) - 1;
          Bukkit.broadcastMessage(Main.instance.getConfig().getString("broadcast-message").replace("&", "§").replace("%player%", e.getPlayer().getName()).replace("%count%", String.valueOf(i)));
        }
      }
    
      static HashSet<Block> diamonds = new HashSet();
    
      public int getDiamondsAround(Block diamond)
      {
        int count = 1;
        int x1 = diamond.getX() - 1;
        int x2 = diamond.getX() + 1;
        int y1 = diamond.getY() - 1;
        int y2 = diamond.getY() + 1;
        int z1 = diamond.getZ() - 1;
        int z2 = diamond.getZ() + 1;
        for (int x = x1; x <= x2; x++) {
          for (int y = y1; y <= y2; y++) {
            for (int z = z1; z <= z2; z++)
            {
              Block b = new Location(diamond.getWorld(), x, y, z).getBlock();
              if ((b.getType().equals(Material.DIAMOND_ORE)) &&
                (!diamonds.contains(b)))
              {
                diamonds.add(b);
                count += getDiamondsAround(b);
              }
            }
          }
        }
        return count;
      }
