bucket not created from bucketclaim

[Torkolis]

I have installed seaweedfs with the cosi driver using the helm chart. This is my values.yml:

master:
  data:
    type: "existingClaim"
    claimName: "swfs-master-data"
  logs:
    type: "existingClaim"
    claimName: "swfs-master-logs"
volume:
  dataDirs:
  - name: data
    type: "existingClaim"
    claimName: "swfs-volume-data"
    maxVolumes: 0
filer:
  data:
    type: "existingClaim"
    claimName: "swfs-filer-data"
  logs:
    type: "existingClaim"
    claimName: "swfs-filer-logs"
  s3:
    enabled: true
    allowEmptyFolder: true
    enableAuth: true
cosi:
  enabled: true
  bucketClassName: "seaweedfs-bucket"
  enableAuth: true
  existingConfigSecret: "seaweedfs-s3-secret"

The BucketClass and BucketAccessClass objects are created sucessfully. Next I create a BucketAccess using the examples (specifying my bucketAccessClassName) and bucketClaim. But unfortunatelly I get no bucket and no secret. These are the logs of the cosi sidecar container, as you can see it doesn't log anything to the bucketClaim or bucket, only bucketAccess, claiming that bucketClaim is not ready:

Also I have checked the master, filer and volume seaweedfs components for logs and can't find anything.
