There was a modification in CreateAssetUploadSession API.

We've been generating the content_upload_url and asset_url based on the file_name parameter value.
However, we discovered that some cases included URL-unsafe characters in the file name, and some publishers don't support URLs with unsafe characters.
Hence, we now always generate URL-safe uploading path regardless of the file_name.
Accordingly, file_name is no longer required field, so you may omit that field.
