invalid configuration for xpack.security.transport.ssl when installing ElasticSearch 8.x

[nahall]

I'm trying to use this Ansible role to install ElasticSearch 8.x. When ElasticSearch tries starting it dies with an error:

org.elasticsearch.ElasticsearchSecurityException: invalid configuration for xpack.security.transport.ssl - [xpack.security.transport.ssl.enabled] is not set, but the following settings have been configured in elasticsearch.yml : [xpack.security.transport.ssl.keystore.secure_password,xpack.security.transport.ssl.truststore.secure_password] at org.elasticsearch.xpack.core.ssl.SSLService.validateServerConfiguration

It appears that some additional configuration needs to be done for 8.x in order to get it to run.

@nahall Did you figure out whats missing?

EDIT:
Adding
xpack.security.transport.ssl.enabled: false
xpack.security.http.ssl.enabled: false
to extra options solved it for my case.
