Update Media Content issue

I attempted to update media content to create an ISO file with Microsoft Deployment toolkit version 8450.  I copied the whole process with error towards the end below.  Wanted to see have anybody else encoutered any similar issues in the past and if so, would appreciate recommendations and feedback.
