cannot deploy Cassandra using k8ssandra

I am using the following chart to deploy a Cassandra cluster to my gke cluster. https://github.com/k8ssandra/k8ssandra/tree/main/charts/k8ssandra

However, the statefulset stuck in state 1/2 (the cassandra container status is always unhealthy)

Here's my values.yaml

cassandra:
  auth:
    superuser: 
      secret: cassandra-admin-secret
  clusterName: cassandra-cluster
  version: "4.0.0"
  cassandraLibDirVolume:
    storageClass: standard
    size: 5Gi
  allowMultipleNodesPerWorker: true
  resources:
    requests:
      cpu: 500m
      memory: 2Gi
    limits:
      cpu: 500m
      memory: 2Gi
  datacenters:
  - name: dc1
    size: 1
    racks:
    - name: default 

stargate:
  enabled: true
  replicas: 1
  heapMB: 256
  cpuReqMillicores: 200
  cpuLimMillicores: 500

kube-prometheus-stack:
  enabled: False

NAME                                                READY   STATUS     RESTARTS   AGE
cassandra-cluster-dc1-default-sts-0          1/2     Running    0          77m

And then I describe the pod

Events:
  Type     Reason     Age                    From     Message
  ----     ------     ----                   ----     -------
  Warning  Unhealthy  2m11s (x478 over 81m)  kubelet  Readiness probe failed: HTTP probe failed with statuscode: 500

Finally, I print the log of the cassandra container.

INFO  [nioEventLoopGroup-2-2] 2022-04-20 11:09:35,711 Cli.java:617 - address=/10.12.11.58:51000 url=/api/v0/metadata/endpoints status=500 Internal Server Error

and the logs of server-system-logger

tail: cannot open '/var/log/cassandra/system.log' for reading: No such file or directory

How can I solve this problem? Thanks.

The message in the cassandra container says it should resolve itself once Cassandra is up and running which is correct.

Similarly no logs are available with the server-system-logger container until Cassandra has started and more precisely, not until the logging framework has initialized.
