Uncaught TypeError: Cannot read property 'toRgba' of null

We're using the ArcGIS JavaScript API version 4.3 to integrate a web map into one of our web applications and we regularly get the following JavaScript error when the map is rendering, and none of the features from the feature layer get displayed. It will work one time, then it fails the next and it seems to be happening more consistently now.

 

Uncaught TypeError: Cannot read property 'toRgba' of null

at js.arcgis.com/4.3/esri/views/MapView.js:414

 

Any ideas on what may be causing this error?

 

Thanks,

Mike...
