Help with publishing error

Feb 15, 2021

Hi, I'm creating a course that is a consolidation of several modules. Each module has it's own quiz and results slide, and then I have a final Results slide that pulls the results from the other Results slides. In order to pass, the user must score 80% or higher on each result. I have created five or six other similar courses with no issue.

The course seems to work ok in Preview, however when I try publishing either to LMS or to Review 360 I get the following error at the point in the publishing process where it is writing the Launch sequence:

<?xml version="1.0" encoding="utf-16"?>
<ErrorReport xmlns:xsi="" xmlns:xsd="">

I am attaching the source file as well. Any help would be appreciated.

Hi Eric!

I'm happy to help! I went through your course and previewed each scene individually. Scene 13  caused an error message, so I previewed each slide in Scene 13 individually, and the error message only appeared when viewing the Results Slide. After deleting the Results Slide, the course was published without an error message.

After deleting and recreating the Results Slide, you should be good to go! If you run into any snags, please let me know!

To anyone else wanting to trouble shoot this themselves - the problem was I had pasted in some content that had unicode that Storyline didn't like. It displays as little squares. Once I had deleted those it worked. For ease I went page by page to preview selected slide, until I found the one that wouldn't display, and then looked through the text in that slide to find those □ characters.
