Array aggregator with Trello cards

[Dac-An]

Hello everyone ! My goal is to automate weekly report from a Trello list “Done”.
I am trying to get all the card of a Trello list but there is no function for that. So I search for card with List ID. I would like to concatenate all the card name into one string to call a chat gpt API.
I have some issues with aggregation and concatenation. Here is the screen shot :

I tried to aggregate by Card names and concatenate with {{join(10.array.name; )}}

Thank you for your time !
