#22932 pantsd not retaining / forwarding http_proxy env vars Issue created by alextremblay Describe the bug Just started using pants yesterday and ran across this error while trying to generate lockfiles:

$ pants generate-lockfiles 
16:20:51.53 [INFO] Initializing scheduler...
16:20:53.64 [INFO] Scheduler initialized.
...
16:29:37.97 [ERROR] 1 Exception encountered:

Pants version tested with pants 2.27 and 2.29 OS Linux Additional info my

pants.toml

file: [GLOBAL] pants_version = "2.29.0" backend_packages = [ "pants.backend.python", "pants.backend.experimental.python.lint.ruff.check", "pants.backend.experimental.python.lint.ruff.format", "pants.backend.experimental.python.typecheck.pyright", "pants.backend.python.providers.experimental.python_build_standalone", ] [python] interpreter_constraints = ["CPython>=3.10,<3.11"] enable_resolves = true [subprocess-environment] # pull in proxy settings from environment and pass them through to all subprocesses env_vars = [ "http_proxy", "https_proxy", "no_proxy", "HTTP_PROXY", "HTTPS_PROXY", "NO_PROXY", ] I suspect #22725 is related. The creator of that issue is getting the same error and also mentions using a proxy. If so, then that person is misattributing their issue to a change in OS or pants version pantsbuild/pants
