What are you seeing?

When I am running the Gitversion tool in my Azure pipeline I am always getting -no-branch- as prerelease label/tag on a develop branch. It is somehow related to the fact that Azure pipelines always checks out in detached head mode.

Strangely I can see in the logs that the branch was properly identified:
INFO [25-05-06 16:39:55:38] Branch from build environment: refs/heads/develop

Interestingly the previously used version of the tool (5.8.1) was providing the "develop" branch configuration "label" value when running on the exact same commit. We would like to get this behaviour back.

Any idea what is going wrong in my configuration?

I am pasting my config:

What is expected?

To get "develop" as "PreReleaseLabel" since the branch name is given via env var BUILD_SOURCEBRANCH.

Steps to Reproduce

#$1 is repo name
#$2 is branch name
#$3 is commit sha1

git init
git remote add origin https://[email protected]/my-org/${1}
git sparse-checkout disable
git config gc.auto 0
git config core.longpaths true
git fetch --force --tags --prune --prune-tags --progress --no-recurse-submodules origin --depth=1  +${3}:refs/remotes/origin/${3}
git fetch --force --tags --prune --prune-tags --progress --no-recurse-submodules origin --depth=1  +${3}
git checkout --progress --force refs/remotes/origin/$3
git submodule sync --recursive
git submodule update --init --force --depth=1 --recursive

log "Unshallowing Git repository"
git fetch --unshallow --no-recurse-submodules
