Hi Loki,
I am trying to override configmap.yaml in loki helm chart 4.6.0 file which controls the storage option using values.yaml file, but have been unsuccessfull till now. Here is what my values.yaml file looks like. I have made sure i am providing a string since if we try to override the config we get following error.

Error: execution error at (loki/charts/loki/templates/validate.yaml:2:4): Top level ‘config’ is not allowed. Most common configuration sections are exposed under the loki section. If you need to override the whole config, provide the configuration as a string that can contain template expressions under loki.config. Alternatively, you can provide the configuration as an external secret.

values.yaml

        role_arn: arn:aws:iam::1233:role/s3bucket
    table_manager:
      retention_deletes_enabled: false
      retention_period: 0

and using this command to template it

helm template charts/loki -f charts/loki/values.yaml --output-dir rendered/loki --debug \

Doing the above i dont get any errors but my changes arent applied to configmap.yaml and deployment doesnt update the storage option. At this time it will be helpful if i can know the ways of overriding the config file somehow.
