`compareAtAmountPerQuantity` incorrect in Product Discount function input
Hello!
A couple of months ago we ran into an odd issue where it looked like the `compareAtAmountPerQuantity` was not being set correctly in the input to a product discount function. Apologies for the terrible screenshot, I'd be happy to provide more specific information via DM.
Because we could not see the input logs when this issue occurred for the merchant, we hard coded checks to panic! when specific `variantIds` did not have the `compareAtAmountPerQuantity` field filled that we knew should have them filled.
The other important note is that this is for the non-default shop currency, which makes me believe this is an issue with markets/functions. If not, it feels very random and does not happen a lot at all for these specific products. Of course, the way we're measuring this is specifically for 2 product variants, so we don't know the potential scope of the issue.
