Failed upload to the LMS

I recently ran into this same issue with SuccessFactors.

There's a 225-character path/filename limit in SuccessFactors - so if you use assets with long filenames, you hit this import error. SAP recommends that path/filenames don't exceed 175 characters, with filenames not longer than 30 or 40 characters. 

You have to edit down the filenames of the assets you drop into your project.
