Transaction queue

Hello, i have a question about an error i get, i have a definition with two python nodes, one that explodes various pieces of geometry and another that fills in some area parameters with the respective area value for that geometry, the problem is that i get this error when i run them: Starting a new transaction is not permitted. It could be because another transaction already started and has not been completed yet, or the document is in a state in which it cannot start a new transaction (e.g. during failure handling or a read-only mode, which could be either permanent or temporary). is there any way to queue up transactions so i can avoid this type of error? Thanks

just put a node called Transaction.End after the first Python node and before the second Python node.
