Go 1.11 application panic after upgrade

[Matt Baer]

After following the instructions for upgrading from Go 1.9 to 1.11 and then running `go run .` as mentioned in the docs, my web application builds, but crashes on the first request it receives:

panic: Metadata fetch failed for 'instance/attributes/gae_project': Get http://metadata/computeMetadata/v1/instance/attributes/gae_project: dial tcp: lookup metadata on 127.0.0.53:53: server misbehaving

This seems like maybe something else needs to be running locally on my machine. But I can't find any information in the docs. Any ideas?

Hello Matt, 

Please note that Google Groups are reserved for general Google Cloud Platform and product discussions and not for reporting issues, which is why I suggest moving the troubleshooting to Issue Tracker, where issues can be turned private in case we need to gather any project specific details.
