item variant using the wrong key?

[paolobln]

Hi, we are using GTM4WP v. 1.20.2 and in the view_item event, the variant key seems to be using the wrong naming convention, as it should be item_variant.

The key cartContent.items[n].item_variant seems correct instead.
If there are any other details I can provide, please let me know.

The line should be this one:

gtm4wp/js/gtm4wp-woocommerce.js

Line 530 in 766dc45

current_product_detail_data.variant = product_variation_attribute_values.join(',');
