Synthesis from different nodes

[mgathena]

Hi all,

I am trying to synthesize from different nodes, something like here in the docs

Note that the router can return something like ['A', 'B'] as well. If it only returns a single node name, everything is fine. Problem is when multiple paths are invoked.

The problem is that the nodes A,B,C in the figure are returning to different variables/keys in the state. How do I ensure that in the synthesis node, it waits for all the results before synthesizing? I manually added a wait statement to check if that (longer duration) state variable is not empty, but it keeps waiting. Multiple routes are being invoked, but the issue is in the synthesis node.
