Warning `tag_filter is not a valid function reference` appears if there is no matching tag?

[nicholas-russell]

I am using this in a monorepo with the following structure:

<root>
app
 └─sub-folder
    └─my-pkg
       └─pyproject.toml

The configuration is

[build-system]
requires = ["setuptools>=61.0", "setuptools-git-versioning"]
build-backend = "setuptools.build_meta"

...

[tool.setuptools-git-versioning]
enabled = true
tag_filter = "my-pkg/(?P<tag>.*)"
tag_formatter = ".*/(?P<tag>.*)"
dev_template = "{tag}+{branch}.{sha}"
dirty_template = "{tag}+{branch}.{sha}.dirty"

Running the command below, without any tag:

~/app/sub-folder/my-pkg$ setuptools-git-versioning
[2024-01-24 15:37:18,569]  WARNING: tag_filter is not a valid function reference: Wrong reference name: my-pkg/(?P<tag>.*)
0.0.1

Now when I do tag something (e.g., my-pkg/1.0.0), it gives me something different

~/app/sub-folder/my-pkg$ setuptools-git-versioning
[2024-01-24 15:38:02,986]  WARNING: tag_filter is not a valid function reference: Wrong reference name: my-pkg/(?P<tag>.*)
[2024-01-24 15:38:03,009]  WARNING: tag_formatter is not a valid function reference: Wrong reference name: .*/(?P<tag>.*)
1.0.0+master.9ff32a07.dirty

If I tag my current commit and have a clean working tree I get below, which is expected, but error messages are confusing. These don't really matter though.

~/app/sub-folder/my-pkg$ git tag my-pkg/1.1.0
~/app/sub-folder/my-pkg$ setuptools-git-versioning
[2024-01-24 15:39:47,446]  WARNING: tag_filter is not a valid function reference: Wrong reference name: my-pkg/(?P<tag>.*)
[2024-01-24 15:39:47,474]  WARNING: tag_formatter is not a valid function reference: Wrong reference name: .*/(?P<tag>.*)
1.1.0

So the crux of the issue is that when there is no tag and a filter, it won't append the VCS info.
