Thanks @Niklas_Hatje ! The reason is that my first node is a webhook (this is the node I get the ItemList from). Then I need a notion node to create a record in a notion databse and set some fields in it. Then the I should make a loop too add more blocks in the new notion record. For this I need the Id of the record coming from the notion node and tje itemlist coming from the webhook. More details in this thread… Loop through json - #3 by One1Tick
Thanks again
