Describe the bug
After PR #13781 has been merged, I'm getting the Please define loki.storage.bucketName.chunks error.

I'm using the monolithic deployment documented here: https://grafana.com/docs/loki/latest/setup/install/helm/install-monolithic/, with 1 replica.

To Reproduce
Steps to reproduce the behavior:

  1. Try to use the Helm values shown in the documentation shown here: https://grafana.com/docs/loki/latest/setup/install/helm/install-monolithic/
  2. observe the error

Expected behavior
The documentation should provide a working deployment.
I'm not sure if the documentation should be updated or the code itself.

The values.yaml seems to be working fine with chart 6.33.0.

Environment:

  • Infrastructure: k8s
  • Deployment tool: helm+flux

Screenshots, Promtail config, or terminal output
If applicable, add any output to help explain your problem.

This is my exact values.yaml:

backend:
  replicas: 0
bloomCompactor:
  replicas: 0
bloomGateway:
  replicas: 0
chunksCache:
  enabled: false
compactor:
  replicas: 0
deploymentMode: SingleBinary

    volume_enabled: true

      schema: v13
      store: tsdb

  resources:
    limits:
      memory: 1Gi

  replicas: 0
read:
  replicas: 0
resultsCache:
  enabled: false
singleBinary:
  replicas: 1
test:
  enabled: false
write:
  replicas: 0

Only changes here is a memory limit for minio, and I disabled authentication on loki, which shouldn't affect the error.

Here's a screenshot of the error (I can't select text from this box, so you'll have to do with this)
