I get an error when I try and pull the Facebook Cost Per Lead (form) numbers into Google Data Studio.
I have set the target as Facebook Ads, Metric as Cost Per Lead (Form) and filtered by campaign. Weirdly, other metrics like Impressions and Leads come through fine.
More weirdly, I can get the Cost Per Lead (form) into a google sheets so it seems to be an error specifically related to Cost Per Lead (form) in Google Data Studio
We investigated the issue and it turn out be a bug in Google Data Studio's way of handling some calculation formulas. We reported this issue to Google (link to issue: https://issuetracker.google.com/issues/74537173) and we hope for you to go and star the issue (star is next to title of the bug report), so Google will know it's important to you too.
Thank you for reporting this issue.
