Explanation

• What is the behavior you expect?
  The chart should show the text configured via the noData option. And not throw any exceptions.
• What is happening instead?
  Rendering the chart throws an error: Uncaught (in promise) TypeError: t is undefined. The chart renders the noData text correctly and there does not seem to be any other issues with the chart.
• What error message are you getting?
  Uncaught (in promise) TypeError: t is undefined

As mentioned, the chart seems to work fine, but the error can cause the application to crash (at least it does in debug mode with React).
