I am trying use a custom app. I have a few cards using it already and I want to create a new one. When I try to save I get a prompt saying: "Error creating DomoApp"
I can do this with other apps and I've done it with this one in the last few months. What could cause this?
I have already tried saving it as a new app. Same issue. So it seems to not like something in my manifest?
When I am attempting to create the card i get a preview of the app and it loads great as you can see here:
But then I still cannot save.
