A quick look seems to indicate that `do_stanza` may sometimes return `None` due to the indentation of the `return` at the bottom. You would need to ensure that `do_stanza` always returns the tuple you expect. > **(attachments)** > > ![image001.png](https://us1.discourse-cdn.com/ansible/original/2X/7/727b31639ee1b5a8e571e19d6ce154eb81193e61.png) > ![image001.png](https://us1.discourse-cdn.com/ansible/original/2X/7/727b31639ee1b5a8e571e19d6ce154eb81193e61.png) ---
