[Box Web UI Elements] Succesfully used?

Has anyone successfully used the Box Web UI Elements component in one of their OutSystems apps?  I would very much appreciate a sort of "Hello, World!" for it.  Pseudo-code would be sufficient.  I have attached my own minimal test app.  It throws an exception.



What's the exception you're getting? Can you give us more detail about it?


NoBoxAuthorizationCode exception.

If I replace the Content_Preview web block with a list widget that takes its input from the output of a Folder_RetrieveItems, it works fine.

Yes, I did.
