This error means that you’re trying to select item number 2 of your list but your list length is 1
how can i solve this ?
Show your blocks
I don’t know what items are in each list but it seems that one of your block is trying to select item number 2 of a list length 1.
It might come from the “select list item list: listitem index: 2” block or the initializing of the local listitem
