Attachfile function using Googlecloud buckets

Hello fellow trailblazers,

I'm currently utilizing Google Cloud buckets to facilitate file exports and imports within SFMC. As part of this process, I'm aiming to attach a file that I've exported to a Google Cloud bucket. Despite my efforts, I've encountered an issue where the emails I'm expecting to receive with attachments aren't coming through.

I suspect that my approach might be incorrect, particularly in terms o#f the parameters required to attach files from Google Cloud buckets. If anyone has experience with this, I'd greatly appreciate your insights. 

%%[ var @fileName, @fileAlias set @fileName = "xxxxxxxxxx/yyyyyyyyyyy.csv" set @fileAlias = "yyyyyyyyyyy.csv" AttachFile("HTTP", @fileName, @fileAlias) ]%%
