08/01/2023, 1:21 PMIs "" the default value you have in your code if the features didn't get loaded?

08/01/2023, 1:23 PMYou might want to change your sql to look at just those 7. Perhaps they all came from the same user, who might be a dev or something trying something out.

08/01/2023, 1:25 PMMy default value is “” but shouldn’t the experiment always assign a variation id ?
If I add a default variation Id wouldn’t that create a bias in the experiment?

08/01/2023, 1:30 PMGood point. No the tracking callback shouldn't be fired if the features didn't load.

08/01/2023, 1:34 PMGiven the small numbers it more than likely did not change the statistical significance of your result.

08/01/2023, 1:52 PMDidn’t find a variation Id = “” row in my table.
Probably something happens when the query is run

08/01/2023, 1:54 PMHmm that is strange. The queries are usually composed of a bunch of subqueries and tables. You could look at those temporary tables that it makes and uses for its sum and compare that sql with the one that you are doing that has no results.
