Hi, we have been successfully running experiments using the Visual Editor (on Shopify, using Javascript). Now we want to run some more sophisticated experiments using feature flags. This is the code we are using as feature flag:

const quizId = window.gb && window.gb.isOn('quiz_subcategories') ? 'id_one' : 'id_two';

The experiment itself seems to be working fine, i.e. the IDs are switched. (tested by previewing the experiment variations) However, the trackingCallback is not triggered. It has been (and is in other experiments) working fine for the Visual Editor though. It seems the SDK is not picking up on the this feature flag. Do we need to add some kind of targeting or activation code? The feature flag was setup in GB and liked to the experiment

Hi Sascha, are you setting the deviceId attribute of the growthbook object?

Hi James. Yes,

deviceId

is set in the SDK attributes. Have been using it in other experiments without issues.

Do you have a debug environment set up where you can use the Growthbook Dev Extension? https://chrome.google.com/webstore/detail/growthbook-devtools/opemhndcehfgipokneipaafbglcecjia

Not a dev environment, but I have the Chrome extension installed and checked it there (we use an

internal_user

flag to not actually send the data to GA4, but dataLayer push should still happen - and does for other experiments). So we can test without polluting the data. dac23-065 experiment corresponds to the "quiz_subcategories" feature flag

No worries. Glad you found it.
