Hi 0hM3N05Y40Hi,
Are you getting anywhere with this? I am having the same issue.
I have a delivery date metafield on my orders, and when I try and call it in order printer with
{{ order.metafields.custom.delivery_date.date | date }}
I get an error “Liquid error: wrong number of arguments (given 1, expected 2)”
If I just use
{{ order.metafields.custom.delivery_date.date }}
it returns nothing even though there is a value in the field.
Arrghh!
