Chart.js not working in Community Lightning Component

Question

In a lightning component inside a Community Builder page, I'm following this guide from the docs exactly: https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/js_libs_platform.htm

In the community builder view, the chart renders as it should. However, when I publish and view the community page, I'm getting a failure on the last line in the controller method:

I checked and the static resource is loading correctly - and debugging is telling me there's an issue with this line:

var myNewChart = new Chart(ctx).Line(data);

Answer 1

So the issue was that on my community page, I needed to "Empty Cache and Reload". Not sure why - but that resolved my issue.
