SYSTEMD_SERVICE_swupdate value swupdate.service does not exist

Question

I am trying to build swupdate image by running bitbake swupdate-image but getting following errors,

ERROR: swupdate-2019.04-r0 do_package: SYSTEMD_SERVICE_swupdate value swupdate.service does not exist
ERROR: swupdate-2019.04-r0 do_package: 
ERROR: swupdate-2019.04-r0 do_package: Function failed: systemd_populate_packages
ERROR: Logfile of failure stored in: /home/panther2/warrior/build/tmp/work/corei7-64-poky-linux/swupdate/2019.04-r0/temp/log.do_package.22017
ERROR: Task (/home/panther2/warrior/sources/meta-swupdate/recipes-support/swupdate/swupdate_2019.04.bb:do_package) failed with exit code '1'

I am building for warrior yocto branch. Error indicates that swupdate.service does not exist but swupdate.service does exist under meta-swupdate/recipes-support/swupdate/swupdate. Any help is really appreciated. Thanks for your time.

swupdate-image is a rescue system - it generates a Ramdisk. Care was taken about footprint - it runs then with SystemV and not with systemd. If you want to buid swupdate-image with systemd as init, add your own swupdate-image.bbappend and rearrange the list of packages.
