I am trying to have a token pull multiple items from a list, then keep these token IDs as an array for each item pulled. When I have the token enter the Pull from List block, it successfully pulls what I want and has an array of the tokens pulled under the token.pulled label. However, if that token continues along and does other operations (like a delay step), the token.pulled label becomes NULL. How do I keep this information in the token.pulled label? Why is it getting overwritten?
