I'm trying to switch over logging in Fleet from

filesystem

to

pubsub

, and I've switched the configs, made the topics, etc. I have the

GOOGLE_APPLICATION_CREDENTIALS

env var set to the filepath of my service account, but I keep getting

Error initializing service: initializing osquery logging: create pubsub status logger: create pubsub client: pubsub: google: could not find default credentials

... has anyone run into this before?
