Restore from cloud to operator

i’m attempting to restore a backup I made with couchbase SERVER onto a kubernetes cluster running couchbase OPERATOR. I’ve created my backuprestore object as per below, and added in a secret for the AWS bucket credentials. But when I apply I get no activity including nothing in the events. Am I missing something big here? (Seems it would at least want a repo name from the existing repo?)

apiVersion: couchbase.com/v2
kind: CouchbaseBackupRestore
metadata:
name: my-restore
spec:
backup: my-backup
start:
str: oldest
end:
str: latest
objectStore:
secret: mysecret
uri: s3://mybucket
