Hi Abou! I can't help with the issue at hand, but as general advice for the future: if you had Salsa-CI enabled at https://salsa.debian.org/pascal-team/fpc/-/pipelines the build-all and build-any jobs would have probably caught this before upload.
Just open https://salsa.debian.org/pascal-team/fpc/-/settings/ci_cd and under "General pipelines" in box "CI/CD configuration file" put "recipes/debian.yml@salsa-ci-team/pipeline" to activate it. It is super easy. More at https://salsa.debian.org/salsa-ci-team/pipeline/-/blob/master/README.md Hopefully more and more DDs adopt Salsa-CI, it is such a time saver! :)
