dataFunction not rendering graph with optional matches where relationships are null

[exoup]

Expected Behavior (Mandatory)

Using dataFunction to render a graph with optional matches (i.e. where nodes may be null) should still render.
This does work when using cypher to generate a graph.

Actual Behavior (Mandatory)

Graphs fails to render.

With consoleDebug: true, the nodes with null never appear in the console log, whereas they do appear when using an initial cypher instead.

How to Reproduce the Problem

Use a datafunction that has an optional match that returns at least one node as null, and then attempt to render the graph.
