Hi team, 👋 I come bearing another question regarding sticky bucketing. I create sticky bucket experiment with fallback attribute as visitor_id (my anon id) and once user logins, I get user_id and set the value using setAttribute(). I have a web application when user land in non-loggedin state but then logins at some point later. After going through the GB documentation i concluded I only need to call setAttribute to set user_id and then later call getFeatureValue for growthbook to pick user_id from attributes. I wanted to verify it via chat gpt, however it's always prompting me to call gb.refresh() after calling setAttribute saying gb would not recognise the updated attribute. However, gb.refresh does not exist! I checked the gb codebase as well and it seems like setAttribute does indeed calls some private refresh fn. So what it is?? Should I call a refresh fn manually or not? I am using vanilla javascript SDK and not any other SDK on top of it

I'm seeing this in the Experiment results tab. Why am I seeing this & how can I solve this?

What is the correct way to update attributes using

@growthbook/growthbook-react

here in docs https://docs.growthbook.io/lib/react#updating-attributes

gb.setAttributes({
  // Only update the `url` attribute, keep the rest the same
  ...gb.getAttributes(),
  url: "/new-page"
})

but I found that there is a method:

gb.updateAttributes()

it spreads previous attributes under the hood. But it doesn't cover in docs. So probably it can be removed in next versions of SDK. What will your recommendation?

Hi, we are using the on premise enterprise version of Growthbook (Build: 3.5.0+4470a21 (2025-03-04) and during PHP SDK selection we only have to option to select until v1.3.0, is this expected and what do we need to do to allow higher version to be selected there? Asking as the free version with cloud does have access to later versions.

Hi! In Fact Table Metric (Retention) is that real to measure retention not from experiment exposure but starting from custom event (like trial started or purchase made)? I didn't find Retention metric description in documentation or Ask-AI.

I'm on a free tier account. Im trying to add a datasource from bigquery but got this error.

Datasource ds_19g62cm9l5lhcb does not exist.

We have a PRO account, using the latest Go client, and we are seeing a lot of connection failure events. Is there an issue on the Growthbook end? Or are we hitting some kind of limit? This is the error we are seeing:

Growthbook SSE datasource","reason":"request failed: connection to server lost: EOF

I can't find any usage metrics in the UI, so cannot really determine what's happening. Any suggestions?

Hi GrowthBook team, I've been evaluating your product for my web project built with React 19. I'm currently using the JavaScript SDK since the React SDK doesn't officially support React 19 yet and according to GitHub issue discussions, AI docs, forum posts, official React 19 support is planned for release with GrowthBook 3.6 (around late April/early May 2025). Is this timeline still accurate, or are there any updates on when React 19 support will be available? Thanks!

Hi! Am I right that if we use in all our tests Exclude In Progress Conversions then using Fact Table Metrics wouldn't increase speed of updating experiments?

Hi guys. We only have 6k users / month, are we correct that's it's way too low to do A/B testing ?

Hi! QQ: is there a way to create a cohort uploading device ids? I have users that haven't been assigned to a user id (anonymous users) but their behaviour is key to evaluate the performance of a feature

We saw documentation on support for targetting conditions using a date attribute (https://docs.growthbook.io/features/targeting#date-targeting) The docs mentions supports as of version 3.1 -> How does this translate to corresponding client-side SDK support or should this work with older client versions? How can we confirm if client side is correctly supported here (we're using the C#/Unity library), we seem to be finding the condition evaluating always to true from our tests

Hey! Asking to see if anyone has suggestions on how I can perhaps approach the date cohorts dimension in the results tab. In other experimentation tools i've used you can see the controls behaviour also for metrics. This was very powerful since I could easier examine if there were any irregular behaviour on a specific day. A scenario could be that I saw a suspicious result for a metric, then I could use a date cohort to see if it was a specific day where this irregularity occurred and take it from there. I haven't found a good way to do something like that more than creating a report and manually changing the date, but it's tedious compared to an overview like the one in the attached image. I've also asked the AI and based on its information the reason is because the baseline is seen as 0% always.

Hey everyone! We’re facing a major issue with GrowthBook in Facebook and Instagram in-app browsers. When a user clicks on our ad link from within the Facebook or Instagram app, it opens our site in a WebView. In this environment, GrowthBook’s feature flag request fails, and we don’t receive the correct flag. This is affecting a significant portion of our traffic — thousands of users — which currently prevents us from using GrowthBook in production. Has anyone else encountered this issue or found a workaround?

Hey team, https://geodehealth.com/ for bot protection and I believe causing the GrowthBook SDK not to work properly despite being added:

Hello, please advise the channel for PRO support after upgrading to GB PRO

for the growthbook proxy, is it possible to use both the origin and the proxy? or is the invalidation only sent to the proxy if you decide to use it, meaning the growthbook cdn will be stale?

GTAG/GA4 Hit "empty": I set up using the recommended code here, experiment is working, however when looking at this in GTM looking at the actual "HIT" the dataLayer for the experiment_viewed event is empty. We verified the set up with GA4/BQ and GB is all lined up. If you look here: www.lapolicegear.com and check the dataLayer in the console you will see it is not empty. So the issue is clearly that the data is being sent to GTM before the dataLayer actually contains the correct info. Setup looks like this:

onReady() {
        const { cartId, secureBaseUrl } = this.context;
        let $body = $('body');
        let $dropdown = $('#cart-preview-dropdown');

        let visitor_id = localStorage.getItem("visitor_id");
        if (!visitor_id) {
        visitor_id = Math.random().toString(36).substring(2, 15); 
        // or any other method to generate a random ID
        localStorage.setItem("visitor_id", visitor_id);
}

let pageType = this.context.page_type;
async function initializeGrowthBook() {
    try {
      // Manually fetch features
      const response = await fetch(`<https://cdn.growthbook.io/api/features/sdk-z2eQdvHSoRomlSFH>`);
      const { features } = await response.json();
      
      // Initialize GrowthBook with the features
      const pluginOptions = {
        trackers: ["gtag"],
      }
      const gb = new GrowthBook({
        enableDevMode: true,
        features,
        apiHost: "<https://cdn.growthbook.io>",
        clientKey: "sdk-z2eQdvHSoRomlSFH",
        plugins: [
          thirdPartyTrackingPlugin(pluginOptions),
        ],
        attributes: {
          id: visitor_id, // Use the anonymous ID for user identification
        }
      });
      
      
      let experiment_set = localStorage.getItem("experiment_key");
      if (!experiment_set) {
        let experimentKey = gb.isOn("groove-mini-cart");
        localStorage.setItem("experiment_key", experimentKey);
        if(pageType === 'product') {
            window.location.reload();
        }
    }


      if (gb.isOn("groove-mini-cart")) {
        console.log("Feature enabled!");
        $body.addClass('in-experiment');
        $dropdown.addClass('cart-dropdown-gb');
        cartPreviewGb(secureBaseUrl, cartId);
        
        
      } else {
        console.log("Feature disabled");
        cartPreview(secureBaseUrl, cartId);
      }
      
      return gb; // Return the instance if needed elsewhere
    } catch (error) {
      console.error("Error initializing GrowthBook:", error);
    }
  }

Hi! Do you know how I could download all the results from an experiment? I need to cross-check the source and device, but it only lets me download one or the other. I’d like to see all the detailed information in one file — is there a way to get the full CSV like that?

👋 Hey folks! We’ve set up a self-hosted GrowthBook instance using the official docs: https://docs.growthbook.io/self-host ➡️ Hosted at: ______(secret) ➡️ Plan to integrate with Adjust via REST API later Main use case: A/B testing + feature flags for mobile products (5–6 apps) Couple of quick questions: 1. What are the key next steps to finalize the setup? 2. Any configs or checks we should do before going live? 3. Can we manage 5–6 separate projects under the same domain? Appreciate any tips or insights — thanks a lot! 🙏

We've set up a self-hosted instance of GrowthBook using the official documentation: 🔗 https://docs.growthbook.io/self-host So far, we’ve: • Deployed a dedicated virtual machine for GrowthBook • Installed all the necessary components as outlined in the guide The service will be available at:

<http://xohi.com|xohi.com>

We’d really appreciate your advice on what steps remain to fully finalize the setup and ensure everything is running smoothly. Are there any specific configurations or best practices we should be aware of at this stage?

Hello, What is the correct way to merge users before login and after, so that experiment variation will not change for the user after he logs in, in our use case, users might use the app before signing in. we set the ID in our frontend like this while using Growthbooks DeviceID

gb. setAttributes ({
id: currentUser?._id ?? deviceld,
deviceld: deviceId,
utmSource: Cookie.get ('utm_source'),
utmMedium: Cookie.get ( 'utm_medium'),
utmCampaign: Cookie.get ('utm_campaign'),
utmContent: Cookie-get ('utm_content'),
}) ;
}, [currentUser, isInitializedl);

Hi team 👋 I'm trying to setup self hosted growthbook - I would like to disable the builtin growthbook SSO which is an enterprise feature. How would I go about disabling the builtin authentication? I've had to change

APP_ORIGIN

and

API_HOST

env vars from default for our gateway setup - I think this is causing authentication to be enabled. Thanks

Hi, I wrote an email last week to the sales team and filled out the form on the website. My company is currently evaluating if GrowthBook would be a fit or not. I asked a simple question but I didn't get any answer so far.

Is everybody on vacation or nobody interested in business?

The question is about the Custom Experiment Fields / Templates. On the site it says that a PRO license would give that feature. In my local installation I got a free trial for the PRO license, but the UI tells me I need an Enterprise license.

We're currently using a Cloudflare proxy that injects GrowthBook onto the

window

object. After the page loads, we create a React instance of GrowthBook using the payload and attributes from the

window

instance. However, our CRO specialist wants the

window

instance removed. I attempted to destroy it using

_growthbook.destroy()

, but it throws an error:

Cannot delete property '_growthbook'

. An alternative would be to inject the payload and attributes directly within the proxy, bypassing the

window

object. However, I'm unsure whether redirect tests would still run as quickly as they currently do. Do you have any recommendations / best practices / docs for this scenario?

Hey everyone! How can I make a filte task_path != 'onboarding' or something like this? This interface lets me only filter by =.
