Unique True/False result for a list

Hi @flows-daniel

thank you so much, it worked like a charm. Below the full flow in case someone is looking for it.

Maybe a pit off topic for this question, but how do I get the customers.id out of the list in case it exists. I used ycmCustomers[email=$portalCustomer] but the answer is null …? If I uses it with ycmCustomers[email=“[email protected]”], then it works.
