Scripts not stacking with function discounts

[theo-radiant]

Having an issue with cart scripts stacking with function discounts. If I use a generic shopify discount code it stacks with the cart script meaning some items have 2x discounts which is expected, however if I then create a discount code via a function discount, it no longer stacks with the script discount and all items have 1 discount from the function, is this a bug?

So:

native shopify discount code + cart script = stacks discounts

function discount code + cart script = doesn't stack, function discount is always applied

I know that the script + function discount is applied because I've been in the same situation as you. Have you made the combination selection? Maybe the issue is related to that. I want to help you, but I need more details. Can you provide more information?

[theo-radiant]

Yeah have tried changing the combination settings and nothing changed unfortunately. Even with a native shopify discount and the combinations disabled it still stacked with the script discount (as I believe combinations are just for multiple shopify discounts rather than discounts + scripts). I tried the function discount with all combinations enabled and disabled and the outcome was the same, only the function discount was being applied

Don't you want Script + Function discounts to work together?

[MastersHub]

I'm running both function discount and script discount together. There might be another issue. It requires checking the codes. I don't have any issues; it works in both scenarios.

It seems it's because it's causing the script to error when the function is running

I'm getting a "can't convert nil into Decimal" error, even with the simplest line item script possible which doesn't make sense:

Output.cart = Input.cart

[MastersHub]

Since I can't see the exact line that is causing the error, I can't specify its exact location. However, if you perform a nil check before the line that is causing the error, the issue should be resolved.

Hi,

The full script contents is the following (only 1 line) and the error is still being caused:

Output.cart = Input.cart

Screenshot here also:

It seems functions are causing the script to error even with nothing in

[MastersHub]

It doesn't give me any errors either. Shopify scripts are behaving a bit oddly, but I am sure that 1 script 1 function is working because I have tested the same combination, and both are working simultaneously. To understand the problem you are experiencing, a detailed examination is necessary. It seems like you opened a single-line code to test. If you delete the current script and create a new empty script, the issue should be resolved. I would be happy to assist. I am looking forward to your responses.

Hello did you find a solution for that?

[MastersHub]

I think it was a momentary mistake. Do you have such a mistake?

[theo-radiant]

I tried a new blank script and was still getting the error

Found a thread on the shopify partners slack with the same issue, seems like it's a known issue - https://shopifypartners.slack.com/archives/C0225DTE1M1/p1697560174116759
