I've been seeing production errors my every script I run in the Script Editor. Everything tested fine but I'm unable to resolve this. Any help would be much obliged. 

 

Below is the script I am running.

Hi, did you resolve this?  I have recently posted a message about "InstructionQuotaExceeded" where customers are created very large carts (entering 1million in the qty etc) & I am interested in ways to detect & prevent such errors. I wondered if you were seeing a similar problem if you're code worked in testing?

Hi everyone,

I worked around this problem by placing some boundary conditions in my code after experimenting with cart sizes & working out where the limits get exceeded.  

I assume these attempts are trying to get free stuff or trying to break the checkout, so if the numbers are too high my code simply ignores the cart & doesn't even attempt to apply a discount...

Here's my main class that handles this before applying the discount code (which I have left out for simplicity). 

class PromotionCampaign
  def initialize(cart)
    @cart = cart
    @Max_items = 20
    @Max_qty = 80
  end
   
  def run!
    if(@cart.line_items.count <= @Max_items)
      if(@cart.line_items.map {|cart_line| cart_line.quantity }.inject(0, :+)<=@max_qty)
        discounted_products = ProductBuyXForX.new(@cart).run!
      end
    end
    @cart
  end
   
end

 Hope that is useful to someone!

Modified your code to accomplish a similar solution, but the result is that if the product max quantity is exceeded, the line item is just removed. We were seeing the all too familiar InstructionQuotaExceeded issue with carts having qty's of 1 million per line item - so this is what we've done. It's a short lived solution since scripts will be going away soon enough; however, some peace in the interim:

 

 

# Prevent Insane Cart Quantities
class CartCleanupCampaign
  def initialize(cart)
    @cart = cart
    @Max_qty = 200 # Maximum allowed quantity per line item
  end

  def run!
    @cart.line_items.each do |line_item|
      # Check if the line item's quantity exceeds the maximum allowed quantity
      if line_item.quantity > @Max_qty
        # Remove the line item from the cart
        @cart.line_items.delete(line_item)
      end
    end
    @cart
  end
end

CartCleanupCampaign.new(Input.cart).run!

check_cart(Input.cart)

Output.cart = Input.cart
