Data status cannot be retrieved for archived data if it was archived with an empty comment
When archiving data using the DMA client, the archive request can be sent with an empty comment. However, if data has been archived with an empty comment, when checking for the DataStatus using the client, an exception will be raised. As in the Archive class, the comment attribute is not optional, and the DataStatus class contains the Archive model as an attribute.
Should the commet attribute in Archive be optional?
