Network Navigator throws an unexpected exception in Power BI Desktop

[stopyoukid]

Customer’s repro steps:
Click on data drilldown and then click on a node and the error occurs every time.
I would also note that the functionality that would be implied by the Visualization pane does not seem to always work for the network visualization…IE none of the color data fields seem to have any effect.

JS Error Message:
Cannot read property 'metadata' of undefined

Stack Trace:
Microsoft.PowerBI.Client.Windows.JavaScriptException: An error occurred while rendering the report.
TypeError: Cannot read property 'metadata' of undefined
