        }
    }

Answer 1

This error occurred because the fileName had a character (in this case, "?") which is not supported. If you can update your code to only allow alphanumeric characters(to be safe), then encoding should work. See the Note in https://learn.microsoft.com/en-us/azure/media-services/media-services-rest-upload-files for a list of unsupported characters.
