<.memcached.addresses>: nil pointer evaluating interface {}.addresses

[rosh0450]

while installing mimir through helm i am getting this error:
Error: template: mimir-distributed/templates/validate.yaml:58:22: executing "mimir-distributed/templates/validate.yaml" at <.memcached.addresses>: nil pointer evaluating interface {}.addresses helm.go:88: [debug] template: mimir-distributed/templates/validate.yaml:58:22: executing "mimir-distributed/templates/validate.yaml" at <.memcached.addresses>: nil pointer evaluating interface {}.addresses

but i have already disabled all the cache:

chunks-cache:
  enabled: false
index-cache:
  enabled: false
metadata-cache:
  enabled: false
results-cache:
  enabled: false

and instead have used redis:

mimir:
  structuredConfig: 
    blocks_storage:
      bucket_store:
        chunks_cache:
          backend: redis
          redis:
            endpoint: redis.mimir.svc.cluster.local:6379
            password: ******
        index_cache:
          backend: redis
          redis:
            endpoint: redis.mimir.svc.cluster.local:6379
            password: ******
        metadata_cache:
          backend: redis
          redis:
            endpoint: redis.mimir.svc.cluster.local:6379
            password: ******
        
    frontend:
      cache_results: true
      results_cache:
        backend: redis
        redis:
          endpoint: redis.mimir.svc.cluster.local:6379
          password: *****

can you share your full values.yaml? I couldn't reproduce with the snippets that you have provided

These are the two files.

i still can't reproduce:

perhaps your helm version is outdated? for me it work with helm 3.14.0 and 3.14.1
