`uv publish` package for the first time, "error: failed to query check URL"

I am trying to use uv publish to publish a new python package to a private registry.

I believe the private registry is a nexus repository.

pyproject.toml configuration

[project]
name = "my-example-package"
...

[[tool.uv.index]]
name = "pypi-publish-private"
url = "https:/mirrors.my-company.com/pypi/simple/"
publish-url = "https://pypi-publish.my-company.com/"
default = true

Command I am running:

uv publish -v --index pypi-publish-private

Output:

DEBUG uv 0.5.10
warning: `uv publish` is experimental and may change without warning
DEBUG Publishing with index pypi-publish-private
DEBUG Not a distribution filename: `.gitignore`
Publishing 2 files https://pypi-publish.my-company.com/
DEBUG Using request timeout of 900s
DEBUG Checking for my-example-package-0.1.0-py3-none-any.whl in the registry
DEBUG No cache entry for: https:/mirrors.my-company.com/pypi/simple/my-example-package/
DEBUG No netrc file found
error: Failed to query check URL
  Caused by: Package `my-example-package` was not found in the registry

I am a bit confused.

• Is there something I am suppose to do before publishing the very first time?
• Since the package has never been published before isn't it expected that the package is not found in the the registry?
• Is my private registry not behaving as expected?

I was able to work around this by using twine to upload the package the very first time. Once the package has been uploaded once then uv publish appears to work as expected.

This might be a real problem -- tagging @konstin for when they're back from vacation.

Just tried the fix. Worked great! Thanks!
