Yes, GA4 does not pass arrays, any except items. To make it work, you can do JSON.stringify for such an array from the web container, so it will be passing in string format and then to get array on server container do JSON.parse via a custom variable
Hi Alex,
thank you. That with stringify i have already since yesterday but what makes me headache is how to do json.parse in server container because there isnt a variable where i can do java or so like in the webcontainer … ?
