Hi all, I believe I have everything set up as described in the docs, using an html tag on the front-end, but I don't seem to be getting an assignment callback If I query the request URL it seems like the feature is defined, but the experiments array is empty:

% curl <https://gb-api.spencerkohan.com/api/features/sdk-CtRoip48W39SQYvy>
{
  "status":200,
  "features":{"show-delivery-time":{"defaultValue":false,"rules":[{"coverage":1,"hashAttribute":"id","seed":"b045dc6d-dbbd-431b-9f0b-f303dd7886cc","hashVersion":2,"variations":[false,true],"weights":[0.5,0.5],"key":"test-experiment","meta":[{"key":"0","name":"contriol"},{"key":"variant-a","name":"variant-a"}],"phase":"0","name":"Test Experiment"}]}},
  "experiments":[],
  "dateUpdated":"2024-10-03T15:01:28.770Z"
}

My experiment is running - is there any step I might be missing to get the assignment? One detail I wasn't sure about: I set my assignment attribute to "id" because I saw this was automatically set by growthbook, but I wasn't sure if I have to do something else to trigger the assignment

the experiment array that's empty there is only for visual editor experiments

ah ok - thanks for clarifying do you know when the tracking callback should fire exactly? I have it defined like this:

window.growthbook_config.trackingCallback = (experiment, result) => {
  console.log('reporting assignment event');
  fetch(trackingEndpoint, {
    method: "POST",
    headers: {
      "Content-Type": "application/json"
    },
    body: JSON.stringify({
      shop_id: "6d259ec9-47dd-4e7e-8be6-cbce1b4e7b29",
      event_name: "userAssigned",
      parameters: {
        experiment_id: experiment.key,
        variation_id: result.key,
      },
    }),
  });
};

but the callback doesn't seem to be firing, even if the feature flag is available I also tried clearing the cookies to get a new assignment and it didn't help

it should fire as soon as a user is assigned

nope nothing

can you share the full SDK implementation you're using?

sure, here's the script:

window.growthbook_config = window.growthbook_config || {};
window.growthbook_queue = window.growthbook_queue || {};

window.growthbook_queue.push((gb) => {
  // Do whatever you need with the GrowthBook instance here
  console.log('growthbook loaded');
  console.log(gb.getAttributes());
  let attributes = gb.getAttributes();
  gb.updateAttributes({
    id: attributes.id,
    anonymous_id: attributes.id,
  });

  if(gb.isOn("show-delivery-time")) {
    console.log('show-delivery-time');
  } else {
    console.log('don\'t show-delivery-time');
  }

  document.dispatchEvent(new CustomEvent("growthbookrefresh"));

  
});
window.growthbook_config.trackingCallback = (experiment, result) => {
  console.log('reporting assignment event');
  fetch(TRACKING_ENDPOINT, {
    method: "POST",
    headers: {
      "Content-Type": "application/json", // specify the content type, if necessary
    },
    body: JSON.stringify({
      shop_id: "6d259ec9-47dd-4e7e-8be6-cbce1b4e7b29",
      event_name: "userAssigned",
      // anonymous_id: experiment
      parameters: {
        experiment_id: experiment.key,
        variation_id: result.key,
      },
    }),
  });
};

And then this is added at the end of the

head

tag:

<script async
      data-api-host=API_HOST
      data-client-key=CLIENT_KEY
      src="<https://cdn.jsdelivr.net/npm/@growthbook/growthbook/dist/bundles/auto.min.js>"
    ></script>

ya, I dont think it is

should I try removing it?

did you ever get this working? having the same issue
