cc @Manouchehri - can u lmk what needs to be in our env to pass this test ?
attaching the test log here: cda0de1d-3851-469c-8851-ef12dc27fab2/jobs/20819/tests#failed-test-0
This allows all of the tests in `test_proxy_server.py` to pass, with the
exception of `test_load_router_config`, without needing to set up real
environment variables.
Before:
```shell
$ env -i PATH=$PATH poetry run pytest litellm/tests/test_proxy_server.py -k 'not test_load_router_config' --disable-warnings
