Using Gitversion on tag based shallow clones

[freakalot]

Hi,

I want to switch to a tag based shallow clone to avoid unnecessary long checkouts on our DevOps system

shallow clone:

git clone --branch <myTag> --depth=1 <repoAddress>

this works fine and the checkout has my tag. When running gitversion now, I get the following error:

my gitversion config is very basic:

mode: ContinuousDelivery
branches: {}
ignore:
  sha: []
merge-message-formats: {}
tag-prefix: 'release/'
assembly-file-versioning-format: '{Major}.{Minor}.{Patch}.{env:uniqueVersionNumber ?? 0}'
assembly-versioning-format: '{Major}.{Minor}.{Patch}.{env:uniqueVersionNumber ?? 0}'

does anyone has a hint what I can do that I can run gitversion on shallow clones based on tags without cloning the whole repo?

I believe this is tangentially related to #4212.
