The node number was given only a few debugger steps previous, from AUGraphNewNode, and there was no subgraph involved...
Further research finds that this will return the audioUnit as nil and no error if the graph is not yet open (created, but not opened).
Couldn't find this in the documentation as a pre-requisite for this call to work. Couldn't this situation instead return an error like kAUGraphErr_GraphNotOpen?

err = AUGraphGetNodeInfo(graph, node, nil, nil, nil, &audioUnit);
with a verified valid graph and node and returning no error, set audioUnit to nil?
