I used GrowthBook on client side using React/Next.js. But it doesn't seem to reflect in realtime the flag value when I toggle it in the GrowthBook dashboard. I have set

growthbook.loadFeatures({ autoRefresh: true })

in useEffect like in the docs at first render/initial webapp load. I'm also using GrowthBook's managed hosting. Anything I'm missing? Thank you in advance.

Love GrowthBook, here with our first issue! On a data-heavy experiment with two primary metrics and three guardrail metrics, we have two failing queries:

500: Code: 241. DB::Exception: Memory limit (total) exceeded: would use 7.46 GiB (attempt to allocate chunk of 0 bytes), maximum: 7.00 GiB: While executing AggregatingTransform. (MEMORY_LIMIT_EXCEEDED) (version 22.3.8.40.altinitystable (altinity build))

These failing queries run quickly in ClickHouse itself. The difference appears to be that GrowthBook runs the queries in parallel. Solutions to our problem (beyond increasing RAM) are something like: 1. Not running GrowthBook queries in parallel 2. Allowing some way to manually update guardrail metrics (so we can run them one at a time ourselves) Happy to provide more info if needed!

Hi Guys, does anybody have experience setting up reporting of GrowthBook experiments in GA4? We've set up custom dimensions in GA4 to retrieve the properties send by GrowthBook, through Rudderstack. The event

viewed_experiment

and properties (

experiment_id

and

variation_id

) seem to come through in the default event report, but within a custom report (explore) it only returns

(not set)

values. Does anybody know how to get the values in a GA4 report, so you can analyse on various metrics and compare Control and Variation?

Hi All! I've managed to get GB set up on AWS, but I'm getting "Failed to send email".

docker compose logs

doesn't seem to show anything regarding the error message. Any suggestions on how to debug this?

Hey Team, first of all thanks for this great tool :) I am wondering whether there are any best practices regarding the usage of feature flags in unit, integration and e2e tests. - For unit tests (Jest): I'd mock the library and set feature flags by using

growthbook.setForcedFeatures

. - Integration (Cypress): I'd mock all network requests. - E2E (Selenium): I could fake the growthbook instance to control the feature flags via an API or mock the proxy. Especially with E2E I am not too happy since it requires a lot of effort and I was wondering if someone found better solutions or could share experiences.

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?

Hi GrowthBook, I'm looking for a feature for Multivariate tests, and I haven't been able to find any. Are there any dedicated ways to do this? (e.g. experiment types, implementation options, ...)

Hi Growthbook team, having the same issue as I described here https://growthbookusers.slack.com/archives/C01T6PKD9C3/p1687531717500479 , I now have 8 A/A experiments running with 8k+ impressions and 1.5K+ conversions but the confidence level and the percent change still fluctuate daily, anything I can do to verify our setup?

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?

Cookie compliance Has anyone found a solution to have the treatment load behind the cookie banner, but delaying writing the cookie, "gbuuid" with variant assignment? Trying to minimize flicker for all new users for above-the-fold tests on landing pages.
