The spinner keeps on spinning and the error in the log of grafana is

Additional information

According to the grafana documentation setting pattern_ingester.enabled: true should be sufficient. and by this issue it should work in scalable mode (SSD) as of Loki 3.3.0 which this bitnami version uses. That issue also mentions that pods are being spun up but I don't see them. The official loki graph makes mentions of this here as well. patternIngester.replicas

Does this bitnami chart not yet support the necessary configuration to get this pattern feature working?
