TSDB migration error

[surekha3]

Describe the bug
We have loki running in simple scalable mode in AWS EKS cluster with 2.8.2 version. Storage format taken is boltDB shipper form. I want to migrate it to TSDB form with object storage as s3. Though it's working well with existing s3 bucket config, when configured TSDB, it's not picking up the same bucket even tried to modified the configuration in many ways

To Reproduce
Steps to reproduce the behavior:

1. Started Loki 2.8.2 version with simple scalable mode in EKS cluster
2. Below is the config used before migration
   loki:
   auth_enabled: false
   externalConfigSecretName: "loki"
   readinessProbe:
   null

-- Limits config

limits_config:
retention_period: 4392h # Adjust as needed - Default retention to 1 month
enforce_metric_name: false
reject_old_samples: true
reject_old_samples_max_age: 168h
max_cache_freshness_per_query: 10m
split_queries_by_interval: 15m

-- Storage config. Providing this will automatically populate all necessary storage configs in the templated config.
storage:
bucketNames:
chunks:
ruler:
type: s3
s3:
region: us-east-1
http_config:
idle_conn_timeout: 300s
response_header_timeout: 300s

-- Additional storage config

storage_config:
aws:
sse_encryption: true

4. Below is the config used for migrationloki:
   config: |
   schema_config:
   configs:
   - from: 2022-01-11
   store: boltdb-shipper
   object_store: s3
   schema: v12
   index:
   prefix: loki_index_
   period: 24h
   - from: 2024-09-07
   store: tsdb
   object_store: s3
   schema: v12
   index:
   prefix: loki_index_
   period: 24h

-- Limits config

limits_config:
retention_period: 4392h # Adjust as needed - Default retention to 1 month
enforce_metric_name: false
reject_old_samples: true
reject_old_samples_max_age: 168h
max_cache_freshness_per_query: 10m
split_queries_by_interval: 15m

-- Additional storage config

storage_config:
aws:
s3: s3://s3.us-east-1.amazonaws.com
bucketnames:
chunks: ""
ruler: ""
region: us-east-1
s3forcepathstyle: true
sse_encryption: true
tsdb_shipper:
active_index_directory: /var/loki/tsdb-index
cache_location: /var/loki/tsdb-cache
cache_ttl: 168h
shared_store: s3

Expected behavior
Data storing in boltDB shipper form should be migrated to TSDB format

Environment:

• Infrastructure: AWS EKS cluster
• Deployment tool: helm
