[V2.13.0] Artifact Registry PyPI Keyring: No credentials could be found.

[lcasassa]

Hi,

I wanted to report that when I upgraded to 2.13.0 from 2.12.0 I see an error. I'm running on google cloud build and error occurs when pulling from a private artifacts registry in GCP using keyrings (keyrings.google-artifactregistry-auth). It should find the default service account through the metadata endpoint.

Step #1 - "Build":   Exception

I downgraded to 2.12.0 and the build works again.

In case you want some context, I am using poetry and the pyproject.toml file looks something like this:

[tool.poetry]
name = "my-other-package"
version = "0.0.0"
description = ""
authors = [""]
readme = ""


[[tool.poetry.source]]
name = "my-package"
url = "https://us-central1-python.pkg.dev/my_project_ip/my-package/simple/"
secondary = true

[tool.poetry.dependencies]
python = "^3.8.13"
my_package = { version = "*", source = "my-package" }

[build-system]
requires = ["poetry_core>=1.0.0", "keyrings.google-artifactregistry-auth==1.0.0", "poetry-dynamic-versioning"]
build-backend = "poetry_dynamic_versioning.backend"

We are experiencing the same for 2.23.1, downgrading to 2.23.0 solves the issues as described by the OP
