Go to Data Sources on the left side and find your datasource. Then fix the Experiment Assignment Query on the data source page

Thanks Luke It worked You're a legend 🙂

Thanks, We had the same error, we can now execute the query. But it shows us "No rows returned". We are also connected to GA4 through Bigquery. We have a question, is it necessary to send the "experiment_viewed" as an event to be able to obtain metrics in the experiment?

Not sure Robert, but I think it is. I did it and created a tag in GTM as well. the part at the bottom of this page should help: https://docs.growthbook.io/guide/GA4-google-analytics

Thanks I'll check it out

Hi Robert, that’s correct, you’ll need to send experiment_viewed so that the analysis can differentiate between users who did and didn’t see the experiment.

Ok, thanks for responding
