Hi @Geool It looks like prestahop_get_budgets is returning undefined at that particular trigger.
To debug why that is, I'd recommend using the debug tools to see what value was passed to the query via additionalScope.
Then, you can try running prestahop_get_budgets with that value hardcoded to see if you still get undefined.
Is there any chance that you're hitting rate limits with the API or do you expect it to be able to handle 500+ calls?
