I think this is related to another question I had asked here: Boltdb-shipper - Can we push indexes/chunks from local instance of loki to GCS Bucket
I will try setting up google client and then see if it picks up credentials from my system environment variables. Since I am running a local instance of loki so I probably don’t have any GKE related setup right.
Anyways, I really appreciate your feedback @rajatvig
