Can anyone tell me why this is happening:

This appears to be a bug in Cloud SDK which is affecting dev_appserver.py when using with App Engine Managed VMs. It does not seem to be affecting App Engine Standard or App Engine Flex environments.
Until Google releases a new Cloud SDK with the fix, you can modify the CLOUD_SDK_INSTALL_DIR//platform/google_appengine/google/appengine/tools/devappserver2/go_managedvm.py file locally as shown below (added both the patchable unified diff as well as before/after just for convenience).
Also consider moving to App Engine Flex since Managed VMs are deprecated and will not be supported after October 27, 2017.
Warning: The Managed VMs beta environment (applications deployed with
vm:true) is deprecated and will be decommissioned. This page is for users who are already using the flexible environment withvm:truein theirapp.yamland want to upgrade to the latest release. If you are updating your application from the standard environment, see the Migrating Services from the Standard Environment to the Flexible Environment instead.
