configMaps in additionalResources of DynamoDB remains blank

[SatoruItaya]

• Environment
  • Kubernetes
    • Amazon EKS
  • Kubernetes version
  • v1.12.7
  • region
    • ap-northeast-1
• I tried to deploy AWS service operator and create DynamoDB as https://aws.amazon.com/jp/blogs/opensource/aws-service-operator-kubernetes-available/
• But a Pod created by dynamodb-app.yaml is repeating restart and the log is following

  $ kubectl logs frontend-c9fdf868f-nzh9w
  Got error calling PutItem:
  ResourceNotFoundException: Requested resource not found
  status code: 400, request id: DIVAFAF9LQD0H4ATP1GTKK3LSFVV4KQNSO5AEMVJF66Q9ASUAAJG

• A DynamoDB was created and I can know it also on AWS Management Console.
• The problem may be configMaps in additionalResources of DynamoDB remains blank after deployment and this is the one which is different from the result written in https://aws.amazon.com/jp/blogs/opensource/aws-service-operator-kubernetes-available/ .

  $ kubectl get  DynamoDB dynamo-table -o yaml | yq '.additionalResources'
  {
  "configMaps": [
  ""
  ]
  }
