Couldn't find the expected Java Key Stores (JKS) files! They are mandatory when encryption via TLS is enabled with Kafka Bitnami helm chart

I'm deploying the kafka bitnami chart with TLS enabled for the external client for testing.

I follow the instruction, however, I've got following error. What is wrong with my configuration?

$ kubectl logs my-release-kafka-0
Couldn't find the expected Java Key Stores (JKS) files! They are mandatory when encryption via TLS is enabled.

Secret Creation is like this.

kubectl create secret generic kafka-jks --from-file=./kafka.truststore.jks --from-file=./kafka-0.keystore.jks

Deploy helm chart is following.

helm install my-release \
  --set externalAccess.enabled=true \
  --set externalAccess.service.type=LoadBalancer \
  --set externalAccess.service.port=9094 \
  --set externalAccess.autoDiscovery.enabled=true \
  --set serviceAccount.create=true \
  --set rbac.create=true \
  --set auth.clientProtocol=tls \
  --set auth.jksSecret=kafka-jks \
  --set auth.jksPassword=<MY_JKS_PASSWORD> \

According to the kubectl describe pod, it looks successfully mounted.

I also test if the keystore works correctly. It looks work.

$ keytool -keystore kafka-0.keystore.jks -export -alias localhost -rfc -file signed_exported.crt
Enter keystore password:  
Certificate stored in file <signed_exported.crt>
