Thank you for your feedback, but I have already tried that. I’m currently using a mapper snap (which maybe the wrong way to do it) used the data once, but there are after errors, because the 2 values are both null.

    What should happen if the values are null? You can either filter those with a filter function:

    $orderLine.filter(y=>y!=null)

    or keep them as nulls with extending the expression with a ternary operator:

    $orderLine.map(x=>x != null ? x.extend({"countryIso" : "GB","sessionId" : "ed7e8228-a82b-44e0-adea-caee6c61a987"}) : x)
