Could someone tell me what would cause this error? Uncaught Error at extendBasis (enclose.js:46). Not sure if this is a bug with d3-hierarchy or just the way I am using it.

I am using a React component based on this which uses d3 (I have updated it to use v4). I am also using React Router to create an SPA. My Bubble chart is on the home route all works fine apart from when navigating to another route and then back again. Once one navigates back to the home route this error occurs.

Any help appreciated.
