I found a potential workaround.
* inside the schroot I deleted the local user defined as 'aborrero'
* then chown the build dir to uid/gid from outside the schroot
(bullseye-amd64-sbuild)root@tools-package-builder-04:/build/toollabs-webservice-Oe7KMY#

-rw-r--r-- 1 18194 500 307011 Sep 10 10:08 toollabs-webservice_0.76.tar.gz
Then the build works as expected:
(bullseye-amd64-sbuild)root@tools-package-builder-04:/build/toollabs-webservice-Oe7KMY#
cd toollabs-webservice-0.76/
(bullseye-amd64-sbuild)root@tools-package-builder-04:/build/toollabs-webservice-Oe7KMY/toollabs-webservice-0.76#
dpkg-buildpackage --sanitize-env -us -uc -b -rfakeroot

Or, is this working because I run dpkg-buildpackage as root inside the chroot?
Anyway I'm not sure I understand that detail about sbuild/schroot:
(bullseye-amd64-sbuild)root@tools-package-builder-04:/build/toollabs-webservice-Oe7KMY#
id aborrero
id: ‘aborrero’: no such user
(bullseye-amd64-sbuild)root@tools-package-builder-04:/build/toollabs-webservice-Oe7KMY#
su aborrero
su: user aborrero does not exist or the user entry does not contain all the
required fields
