Hi growthbook team! Yesterday we implemented an experiment, which is being triggered correctly, we see all the right events. However, results on growthbook are not updating. And get this error message. Metrics are also added correctly. We are using an activation metric though. Anyone can help understand why data is not updating? @fierce-painter-54384

Hi Elisabetta. And what do you see when you click on "Update data" purple button?

Hi! Yes 🙂 It keeps saying not data yet, even we do see the experiment being triggered and users going through the flow

After you click Update Data, you should be able to click the three dots and see "View Queries". Those are the actual queries you are running against your database. You can try and run them directly against your database yourself to try and figure out what is going on.
Did you remember to send the tracking event to your data warehouse??
within trackingCallback function?

Hi @white-fireman-22476, yes, we have it in trackingCallback function. So let's say that we have the same configuration for staging and production. The only difference is the data source of metrics from Mixpanel. What would you suggest to look at?

Are you sending things to a datawarehouse with Mixpanel?

Yes, we can see Experiment Started events

So you are still using JQL? As we say at the top of our docs for mixpanel they have placed their query language in maintenance mode and you might consider forwarding the data to a different datawarehouse: https://docs.growthbook.io/warehouses/mixpanel
That said if it is working on staging but not on prod then something must be different about prod datasource. Do you see anything on the metrics page when running the query there?

Yes, when i run queries on Metrics, data is there and that's why we need help understanding why the experiment data is empty. Both, the activation metric and goal metric is showing data.

And you are seeing the experiment started events with experiment_id "quiz-experiment-prod" within Mixpanel? Is there a way to run JQL directly within mixpanel where you can copy the sql that is run on over?

I can answer this: Yes, we do!

the activation metric could be the cause

can you try removing it? Are you sure you need it
