Trying to use dbeaver for open distro for elasticsearch

[fat]

I am running Open Distro for ES using docker with the follow docker-compose.yml

version: "3"
services:
  elasticsearch:
    image: amazon/opendistro-for-elasticsearch:1.4.0
    ports:
      - 9200:9200
      - 9600:9600 # required for Performance Analyzer
    environment:
      - discovery.type=single-node

Curl works ok

$ curl -XGET https://localhost:9200 -u admin:admin --insecure
{
  "name" : "c0d9bc87883b",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "WyiseeK1QlCBExKKL2-RCw",
  "version" : {
    "number" : "7.4.2",
    "build_flavor" : "oss",
    "build_type" : "tar",
    "build_hash" : "2f90bbf7b93631e52bafb59b3b049cb44ec25e96",
    "build_date" : "2019-10-28T20:40:44.881551Z",
    "build_snapshot" : false,
    "lucene_version" : "8.2.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

However on DBeaver, it doesn’t. The error message is

unable to find valid certification path to requested target
