Story telling web app error

Question

I am trying to create a web app using the Storytelling text and legend app. I added 4 web maps to it but when I try to launch it I am getting the following error.

"Unable to create map:

Cannot read property 'baseMapLayers' of undefined.

‌Anybody else experience this?
