Description
I ran the sample project provided and it opens up the web view window but it is blank and url doesn't load.
The following error I'm getting on running adb DEBUG:
NullReferenceException: Object reference not set to an instance of an object at SampleWebView+c__Iterator0.<>m__0 (System.String msg)
at WebViewObject.CallFromJS (System.String message) [0x00000] in :0

Research direction
Start by tracing the SampleWebView.Start iterator and the WebViewObject.CallFromJS call named in the stack trace. Reproduce the blank web view with the sample project and adb DEBUG output, then identify why the callback reaches a null object. Done means the URL loads without the reported NullReferenceException.
