The issue you’re encountering seems to originate from the event scope of your dimension. When mapping certain types of data in GA4, specifically involving metrics and dimensions, it’s crucial to understand their scopes. User (or broader) scoped variables can encompass the data from event scoped ones but not vice versa. Therefore, when you pull in data from the API, concepts like ‘totalUsers’, ‘newUsers’, etc., which are user-scoped, can’t be correctly captured under an event-scoped dimension such as your ‘exp_bucket’. Your concept of using ‘ab_test_lane_[1|2|3|4|5]’ as a user dimension might help you bypass this scope conflict. However, you’d indeed need to manage the complexity of mapping live experiments to these lanes carefully to avoid inconsistencies in the data.
