Loki Helm Chart Configuration Issues (use_thanos_objstore)

Grafana Loki
1

I recently installed Loki using a Helm chart. Since I saw that use_thanos_objstore will become the default way to configure storage in a future release, I enabled it. However, as this seems to be a recent decision, there are still issues with the Helm chart.
Below are the information and issues I am facing:

Helm chart version: 6.27.0

Values:

deploymentMode: SimpleScalable

loki:
  storage:
    use_thanos_objstore: true

    bucketNames:
      chunks: dummy-value     <--- I have to use this to prevent an error

    object_store:
      type: s3
      prefix: null            <---- this seems buggy and need to be removed

Pods:

loki-backend-0                                         1/2     CrashLoopBackOff   11 (2m4s ago)    33m

Error logs:

failed parsing config: /etc/loki/config/config.yaml: yaml: unmarshal errors:
  line 32: field prefix not found in type bucket.Config
  line 92: field prefix not found in type rulestore.Config. Use `-config.expand-env=true` flag if you want to expand environment variables in your config file

I have faced the same issue during the update of Loki Helm chart to the 6.27.0 version
