However, this should not be a failure, instead we should just default to "raw". This allows commands like "fastboot format:ext4 userdata" to work if userdata didn't already have an ext4 partition table (or if FS_EXT4 is disabled in U-Boot), as failing to determine the current partition type is not an error in this case.
