Hi , how exactly does growthbook work with google analytics ga4 ? I am sending my variation id and experiment id in an event name called viewed_experiment , and I am having a separate purchase event which is being send to analytics. My question is how does growthbook indentify from which variant the purchase has happened?

Hey, my growthbook server crashes as a result of these excpetions: "Error: Cannot use JWT_SECRET=dev in production. Please set to a long random string." Perhaps someone have an idea what is the root cause of the problem?

Hello 👋 Did anyone managed to integrate growthbook with nextjs middleware + Segment? Trying to utilise the trackingCallback but it seems like

analytics-node

and middleware might not be so compatible.. Been patiently waiting for the follow up on this article: https://dev.to/jdorn/ab-testing-with-the-new-nextjs-12-middleware-54j6 😄 thanks!

hi all! is there a recommended way of handling the case when self-hosted (or any) growthbook service goes down and other services rely on it? the naive solution is to hardcode fallback values in the codebase but is there any other option?

Hi GB team. We are using Clickhouse as our data source. And we found a timezone issue about the experiment query. Bellow is a query sample about experiment. It used

toDateTime

to filter the timestamp. And we use the UTC time in the experiment settings. but by default Clickhouse is using the server timezone which is not UTC. so the fix should be add UTC in the toDateTime function like this

toDateTime('2023-02-24 17:00:00', 'UTC')

Can anyone help on this?

__experiment as (-- Viewed Experiment
    SELECT
      e.user_id as user_id,
      toString(e.variation_id) as variation,
      e.timestamp as timestamp,
      e.timestamp as conversion_start,
      
      dateAdd(hour, 720, e.timestamp) as conversion_end
    FROM
        __rawExperiment e
    WHERE
        e.experiment_id = 'SOME_EXP_ID'
        AND e.timestamp >= toDateTime('2023-02-24 17:00:00')
        
    )

Hey all, I am just starting to use GrowthBook and I have issues to set my first binomial test. What I did so far : 1. I created a datasource including all users (only logged users, no anonymous) with the experiments & variations they are in. I set the timestamp using their entrance in the A/B test. 2. Then, in my metric definition, I just list users that activated a feature, with the first timestamp at which they activated the feature. 3. I created my experiment by setting experiment ID, variation IDs, start date & end dates. I also set conversion delays between 0 & 24h because it's the way we want to follow-up on this activation. But I have an issue when it comes to analyzing the results of the A/B test. My two cohorts (default & test) have 100% conversion on the activation of the feature. Did you already experiment something like this ? I guess I haven't set properly my datasource/table but I don't really understand how to deal with it right now. Any hep would be more than welcome !

Hi Actually I would like to pull data from Google Analytics (Universal) I added my Google Analytics account, but when testing the data it is throwing error Like viewId is invalid Can you please help me to get rid from this issue

I'm trying to install Growthbook for nodejs and keep getting this error:

SyntaxError: Named export 'GrowthBook' not found. The requested module '@growthbook/growthbook' is a CommonJS module, which may not support all module.exports as named exports.

Im testing this in a barebones sveltekit/typescript project and just by importing growthbook it throws this error at build time. This is my import - copied from docs:

Import { GrowthBook } from “@growthbook/growthbook”

This is a barebones, fresh sveltekit app I'm testing on. Runs fine during dev but fails at build. Does anyone have any ideas here ?

what kind of API rate limit do you have? in your hosted version?

Hi, a general question. what’s this
