Hi All, I was helping someone try to debug their GrowthBook set up and had a basic setup question that I wasn't real sure about that I was hoping someone could answer. I've attached a copy of an experiment they are running showing the Configure Experiment Analysis screen and called out a couple of areas of interest for me. 1. I've confirmed that this database exists and that the connection is working correctly 2. Where is this table supposed to be coming from? Is that our responsibility to manually set up? 3. What happens if this column is not there will it fail silently and just say no rows returned or will it give a more detailed error. Right now I don't have direct access to that DB to confirm manually but I suspect that entire table doesn't exist and I am not sure where it is even supposed to come from yet.

Hi GB! We’ve been running GB on K8s and recently, we’ve started getting errors along the lines of

Error connecting to the GrowthBook API at <https://api.growthbook>.[...].com

with the

Failed to fetch

error. When we try to manually request the API, we get the following

❯ curl <https://api.growthbook>.[...].com

<head><title>502 Bad Gateway</title></head>

Looking at the logs, it seems like the main application pod encounters the following error:

The fix that has worked thus far is restarting the pod hosting the frontend/backend. However, we were wondering if there is a way for the system to failover. Even though ``yarn start` failed with exit code 1` , the application pod was deemed

Running

on K8s. Since both back-end and front-end are packaged into one container, what is the best way to perform a liveliness and readiness probe on the application so that it checks both the front-end and back-end system? Many thanks in advance!

Hi, I met a issue about self-hosted, it shows CORS error when open the login page as it try to connect to the 3100 port which is different than our domain name and default 443 port. So wondering if there is any config that can allow multiple origin name to bypass the CORS error? Or is the 3000 and 3100 serve totally separate path, then I can add rule to route the request in our Cloudfront config

Hi all. We ran into a problem trying to connect GrowthBook to our SPA site. We initialize the GrowthBook, set the user attributes, then call the isOn method. isOn always returns the correct value, but trackingCallback fires ONLY if the user lands on a page where isOn is called. If the user hits it via SPA transition isOn returns correct value, but trackingCallback is not fired, even if isOn has not been called on this feature before.

Good morning. We're getting some Multiple Exposures Warning and Warning: Sample Ratio Mismatch (SRM) detected warnings on multiple experiments. We are using GA4/BigQuery. Nothing has changed in our implementation. The experiments we run have been implemented in the same fashion since we started doing them back in September. We turned on streaming a month ago but this only started the last week. Any ideas on what we could look at outside of what's in the docs? I don't see any issues with how we run the experiments.

hey guys, do you know if there is a delay between when events show up in Mixpanel and when they are available to be queried by Growthbook? I confirmed our new experiment has started and is generating events in Mixpanel but when I press update data in Growthbook it’s saying no data
