`bazel run //:requirements.update` works, but `bazel test //:requirements_test` fails

🐞 bug report

Affected Rule

The issue is caused by the rule: compile_pip_requirements

Is this a regression?

I did not try earlier versions.

Description

bazel run //:requirements.update successfully resolves dependencies to requirements.txt.
However the test automatically created by compile_pip_requirements fails.
I'm somewhat confident that this has to do with authentication. I am behind a corporate proxy and use a .netrc.
I found #1087 which has had no activity or resolution, but sounds related.

🔬 Minimal Reproduction

# BUILD
load("@rules_python//python:pip.bzl", "compile_pip_requirements")

exports_files([
    "requirements.in",
    "requirements.txt",
])

compile_pip_requirements(
    name = "requirements",
    src = "requirements.in",
    requirements_txt = "requirements.txt",
)

# requirements.in
numpy==1.26.4 # pinning numpy to 1.26.4 as per https://github.com/numpy/numpy/issues/23808 allows us to use python 3.12
asammdf
cogapp
docker
jsondiff
pytest
pytest-cov

Hi,
took me ages to find that out myself. Your issue is likely the same as #1817
