I'm not sure you're still looking for help, but, I found your post and used the software I wrote to validate your feed file. You have several problems with the 'bitRate' field on your shortFormVideos. They are actually integers and not 'float' values. For future reference, your feed file is representative of a Direct Publisher channel. Here's the errors I found:
