Looks like this issue is flaky. :worried:

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (38cc183f93c99531e752f4d8d1c43b5751b4f776), this test passed in one build (https://github.com/GoogleCloudPlatform/cloudsql-proxy/actions/runs/2844125508) and failed in another build (https://github.com/GoogleCloudPlatform/cloudsql-proxy/actions/runs/2837019969).
