google-cloud-go: intermittent invalid credential errors

Client

Pubsub

Describe Your Environment

Docker container running on a GCE instance.

Expected Behavior

No intermittent auth errors.

Actual Behavior

We occasionally see

rpc error: code = Unauthenticated desc = Request had invalid authentication 
    credentials. Expected OAuth 2 access token, login cookie or other valid authentication 
    credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.

From sub.Receive. If we wrap the Receive call in a retry, this issue clears up within about a second.

Running on 0.25.0 of this library.

Whoops! Generally, you’d just keep the pub/sub client open for the duration of your program’s life.

Well, this is embarrassing, we were closing the pubsub client early.
