ansible-kafka-admin: Unable to get Topic Information when connecting to a Cluster using SSL

Hello,

first of all, I would like to thank you for this brilliant project. We are starting to implement Kafka and want to manage topics through Ansible. That said, this project fits perfectly. However, I just faced an issue, which might already be referenced in #123, but my error is slightly different. Here are the details:

Expected Behavior

run task kafka_info with resource: “topic” and get a list of all available topics

Actual Behavior

Ansible playbook stops with an error:

Additional information

1. The same playbooks can successfully retrieve the broker and the topic-config through the kafka_info module. It only fails when I want to retrieve the topic information.
2. The CN of the certificate is a super user of the Kafka Cluster.
