More details:
- Rolling back to 45 (which I'm going to roll out on the public sites fixes it).
- It only seems to happen when more than one chart is loaded

Hi Sidd,
I'm not seeing a problem now, though I don't know where to look on the advisorhub.com site. Can you point to a page where there is a problem? Were you using 'current' before changing to '45'?
If you are calling google.charts.setOnLoadCallback more than once, be sure you call it only *after* the corresponding google.charts.load call.

I rolled them back to 45. I'll setup a demo for you a little bit to show you the error.

I see the error, but I can't tell why it is happening. It is handling a resize event, and it appears the element it is trying to detach event handlers from is missing (null). Perhaps that is enough of a clue about what is happening. You may be able to work around this by making sure the elements associated with charts remain in existence throughout the life of the chart, and that ids are not used more than once.
Nothing was changed recently except the loader, so perhaps this is not really a new problem, but the timing of how charts are loaded has changed such that a previously unexposed timing problem is now exposed.

The ids are only used once and the elements stay on the page for the life of the chart. However, the elements may not all load simultaneously. Each element loads independently and uses requirejs to require the google chart library.
