Resources attached to courses give error message from LMS
I have 94 courses, all of which should have documents (PDFs) attached. I attach them and get no error messages. I publish the course and then upload to the LMS. Out of 94 courses, 14 had resources that gave me the attached message. Sometimes I get it on 1 of 2 documents for a course, sometimes for both documents, sometimes both documents work. I have cases where a document is available in 1 course but not available in a 2nd course. Once I get the error in a course, I always get it. When I go back to Storyline, delete the resource, the re-add it and publish, I get the error again. So far my best answer has been to remove the resource from the course so the user doesn't see the error, but the resources are an important supplement to the course. What is happening here, and is there any way to tell if the situation is gong to happen before it gets to the LMS?
