I have installed the operator by helm:

`helm install elastic-operator elastic/eck-operator -n elastic-system --create-namespace --version 1.4.0`

And Elastic node by:

> ```
> apiVersion: elasticsearch.k8s.elastic.co/v1
> kind: Elasticsearch
> metadata:
> name: quickstart
> spec:
> version: 7.11.2
> nodeSets:
> - name: default
> count: 1
> config:
> node.store.allow_mmap: false
> 
> ```

and I am getting below error:
