Hello we are moving to a hosted feature flag system and on launchdarkly it seems like pushing feature flags to the flag management platform is an enterprise feature so I started looking for alternatives. I was going through the growthbook docs but it's unclear how this is here. Basically: I want the developers to be able to define the feature flags in code and push it via CI/CD. Ideally (optionally) define basic on segments like “beta users” without causing the config push to undo changes like enabled for specific users done on the management platform.

Hello, could you please help me debug the issue (or point me somewhere) when setting up AWS Athena data source? I’ve just started Growthbook via docker-compose file from the documentation. When defining Athena data source, we’re getting (actually both me and my colleague)

The security token included in the request is invalid.

, although we’re filling freshly get credentials - outputs of

aws configure get stag.aws_access_key_id

and

aws configure get stag.aws_secret_access_key

(

stag

is name of the profile) Thank you cc @thousands-park-56020

Hey All, What's the threshold for an experiments value change to be flagged as a "suspicious result" and can I configure this somewhere? I have an A/B test that's caused a significant change in metric hits but that's not necessarily unexpected

Hey team. Probably a super noob question, but why don't I see an "update" button (to refresh the dash) when I look at GrowthBook dashboards. I've seen that my colleague have one. Is it a permissions thing? My profile shows I am tagged as a "collaborator"

I could use a hand if anyone is available. I have a feature setup in the Cloud version that I have implemented in my Nextjs React app, but the feature always comes back as

null

. Any idea what I'm doing wrong. It appears to be fully published

Afternoon folks. Anyone successful at standing up growthbook on AWS ECS? I can’t get the growthbook service to stay healthy on ECS, it keeps killing and respawning the task. Using a Docker ECS context, I’ve deployed the docker-compose.yaml to ECS.

Hello GrowthBook! I'm currently trying a visual experiment that gives me this code sample

{
  "mutations": [
    [
      "#__next > div:nth-child(1)",
      "set html",
      "Foo bar version"
    ]
  ],
  "css": ""
}

Where do I need to put it in order to have my experiment displayed in my website?

Hi GrowthBook guys, I'm trying to structure a preliminar implementation here for our SPA, but I'm a little confused about building feature flags based on unauthenticated versus logged in users. 1. How to deal with unauthenticated users, for example, if we want to have feature flags or A/B tests on pages of our sign up process, before authentication takes place? I mean, considering that a unique id is needed to ensure A/B to work properly. 2. And how do users can be bound to previously unauthenticated data as soon as the authentication happens, ensuring the same "person" is tracked properly between unauthenticated and logged in tests?

As part of my GrowthBook POC, we set it up growthbook instance on a EC2 instance, with little to no modification of the

docker-compose.yml

that came with the git repo. And we defined data sources and metrics using the web UI forms. I am guessing that all the meta data is being stored in mongoDB. However, when we restarted the docker container using the following commands , I lost all the metrics, exposure and other definitions. I also lost users who registered. I am sure there is a better way to stand it up so as to persist across restarts? Any suggestion is appreciated

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 ?

I created an experiment

page_split_about

, I also have an experiment analysis linked to

page_split_about

. Clicking on this even redirects me to the correct Feature. When I access the Feature and select "View results" it says, "We couldn't find an analysis yet for that feature. Create a new one now." This is clearly incorrect, can someone please help me understand what I am doing wrong here? Thank you for the assistance

Maybe I’m missing something, but is there a documentation on what

Segments

does? I can’t find it under https://docs.growthbook.io/

It seems like I have everything working but it doesn't appear to work consistently. I keep adding and deleting tests to ensure I understand the workflow but sometimes they work and sometimes they don't. I am setting them up the same way over and over. Has anyone else encountered this?

Hello folks! I wanted to double-check what happens when an experiment ends. Are the following true? Thanks! 1. If we're using the feature flag experiment rule to do the randomization and then end an experiment with the variation as Won, that doesn't automatically disable the experiment override rule in the associated feature. Unless we disable the experiment override rule, the variation will still only be shown to a random half of users. 2. If we disable the experiment override rule and don't add any others, then if the feature is enabled in production, the variation will be in effect for all users. 3. If we disable the production feature flag associated with an experiment, the variation will no longer be shown in production. And separately from experiment ending, I'm wondering what happens when we delete teammates from an account. Does that delete any change history, etc. associated with them? Is there a way to disable teammates that are no longer actively using GrowthBook and then reactivate down the road? Thanks!

Hey! When upgrading Next from 12.1.6 to 12.2.3 (for the stable Middleware release), I get the following error from the

trackingCallback

function, which runs inside the root Middleware function (

middleware.ts

):

error - unhandledRejection: TypeError: fetch failed

      at httpNetworkFetch (evalmachine.<anonymous>:3657:65)
}

Here’s how my tracking callback function looks:

trackingCallback: async (experiment, result) => {
  // Track experiment result with Rudderstack
  await fetch(`${rudderstack.dataPlaneUrl}/v1/track`, {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      Authorization: `Basic ${rudderstack.basicAuthHeader}`,
    },
    body: JSON.stringify({
      anonymousId: anonymousId,
      event: "experiment",
      properties: {
        experimentId: experiment.key,
        variationId: result.variationId,
      },
    }),
  })
},

I’m using the latest version of

@growthbook/growthbook

, tested that the tracking URL of Rudderstack is valid, and have verified that the error does not happen with Next 12.1.6. Has anyone else experienced this error – and maybe found a solution?

Hey guys 👋! Does Growthbook have slack integration? I saw documentation and could not find it anywhere. Any ideas how I can send feature enabled/disabled/added notifications to slack?

👋 Hello, team!

I am exploring growth book self hosted version for ab testing

I dont see Java sdk for back end

Can we use api to know whether user belongs to which variant for an experiment

?

if we use this library on client side for a/b testing then how does percentage wise distribution occur. Client state is not shared between users so whoever loads website will try to assign percentage distribution from scratch regardless what experiments other users are assigned? which will be incorrect way of a/b testing

trying first time and getting this error. Anyone knows how to solve this? Error in function feature in ./node_modules/@growthbook/growthbook-react/dist/esm/index.js:51 growthbook.feature is not a function.

Hello everyone, I'm new with GrowthBook and I'm trying to implement it in my NuxtJS project. Is there anyone who worked with Nuxt before? Maybe stupid question but for me this code is not working:

Even I created 'job-cards' feature and it is a boolean.

Also in call I can see all my features and the call doesn't fail

Hello everyone QQ Is it possible to get the list of tags of the feature as part of the https://cdn.growthbook.io/api/features/ response?

trying growthbook first time what is the difference between features and experiments in growthbook dev tools?

Hello everyone, does someone knows how can I connect my Matomo (before Piwik) to GrowthBook?

Good afternoon everyone, how do I extract the test result per day?
