Hi, I am trying to following the tutorials in this webpage
https://aiida.readthedocs.io/projects/aiida-core/en/latest/howto/query.html#how-to-query
I chose the calculation node 17
:~/AiiDA$ verdi node show 17

node.res works , but list(node.res) does not.

Similar situation happens for node pk=3 and so on.
What is the problem?
Many thanks!
