Next server-side example and A4T reporting

Hi!

I've took the next-server-side-rendering-demo example and tried to implement A4T reporting according to this doc

I've updated all static files (AppMeasurement.js, at.js, VisitorAPI.js), target-config.json and added the following changes to the helpers/target-server-side.js

After running the code, I was hoping to see the corresponding A/B test report in Adobe Analytics, but I don't see any reports.

My A/B test has been created with form composer, where I've defined a simple JSON offer (feature flag) like

A experience
{
    "value": false
}

B experience
{
    "value": true
}

Have I made something wrong or missed something? Or maybe A4T reporting doesn't work for form composer?
