Hi Dan-Hrpr,
This doesn’t seem like you’re running into a limit (e.g. instruction count limit or input query limit).
Specifically, the error message “TypeError: cannot read property ‘reduce’ of undefined” makes me think it’s a JS runtime error.
If you console.error the input when your function runs, you might be able to identify the cause. Maybe selectedProducts, or one of its properties, is undefined.
Best,
Tobe
