Local build/run works, Galaxy deploy issue with specific package

Hi, I need some help please. I am running Meteor METEOR@1.4.2.3

I am using a 3rd party NPM package https://www.npmjs.com/package/personality-sunburst-chart

It runs fine locally, I can render the Sunburst charts. Meteor build locally and it succeeds.

When I try and deploy to Galaxy, I get the following error https://github.com/personality-insights/sunburst-chart/issues/20

I see issues like https://github.com/meteor/meteor/issues/5517 phew long thready… but trying to work out where the issue is.

Any help appreciated? I’ll log with Galaxy Support too, but I expect they’d say this issue is relevant to the package.
