If there are more archives with different btypes inside build, some can take priority. Case which hit this: CG imported new build, which contained 'image' and new 'operator-manifest' btype archives. As listArchiveFiles checks one by one for maven/win/image/other btypes and call different listing handlers, 'image' will match first and call get_image_archive(archive_info['id'], strict=True) which raises an exception as in image_archives nothing matches this archive_id.
