Hello friends, I am trying to install OpenSearch and its dashboard on Kubernetes Cluster using Helm Chart. I am getting below error message while installing dashboard. Please advise.

This error is being emitted by OpenSearch Dashboards, correct?

I think this has something to do with OPENSEARCH_HOSTS in opensearch_dashboards.yml

Now the dashboard is loading after adding the following configuration parameters in opensearch_dashboards.yml. Thanks for your direction to resolve the issue.

opensearch.hosts: [https://:< OpenSearch port >/]
opensearch.username:
opensearch.password:
