This is stopping a significant development for us using the new & updated tools from Esri so would like it resolved. Any input and ideas really appreciated.

Deidre Wolf Thank you! This tip worked wonderfully. I appreciate the help!
This issue is caused by the header, button, or body properties in the sharedTheme object returned from the Portal to be null. Usually, it would return an object as:
{ header: {}, body, {}, button: {}, ... }, which the properties are not empty.
I will look into this, and in the meantime, please add a logo, or colors to the header, button, or body to force the sharedTheme to not be null.
Yiwei Ma Thank you! I appreciate the help and work you do!
