I can't answer your build-error question, but:
Not sure if it is the same device, but you can have a look here:
https://gitlab.com/ubports/porting/community-ports/android11/samsung-galaxy-note-10-plus
I would advice you, to clone a repo of the community builds, which matches your device most.
Then adjust it, according to your device (deviceinfo, overlays). And try to build it using build.sh.
Next to the samsung-community-repo, there are other, more up-to-date repos, which make use of the halium-generic-build tools: https://gitlab.com/ubports/porting/community-ports/halium-generic-adaptation-build-tools
You can see this repo, how they get integrated: https://gitlab.com/ubports/porting/community-ports/android9/oneplus-5/oneplus-cheeseburger-dumpling (.gitlab-ci.yaml, build.sh)
Its not recommended to use the fullsystemimage build-variant. (Even though, making halium-boot is not the reason).
