I've been running an app in managed Cloud Run for months, and thought I'd try getting it up and running on GKE / Anthos. Followed the setup guide with little trouble. I'm stuck, now, though. The following error occurs on my standard image as well as one I made with modifications to ensure all the logging went to /dev/stdout thanks to suggestions found in this thread. Am I missing something obvious?

Note that Kube shows no running pods and the logs are empty.
