I'm using Using latest landoop/fast-data-dev image (but the Kafka cli tools are the same as upstream)

When trying this command within the container:

root@fast-data-dev / $ ./opt/landoop/kafka/bin/kafka-topics --bootstrap-server hostname:9093 --command-config client.properties -list

I get this error

[2020-11-26 18:09:01,580] WARN The configuration 'ssl.truststore.location' was supplied but isn't a known config. (org.apache.kafka.clients.admin.AdminClientConfig)

Here is my client.properties file

security.protocol=SSL
ssl.truststore.location=/data/cluster-crt/ca.p12
ssl.truststore.password=valid_password
ssl.keystore.location=/data/user-crt/user.p12
ssl.keystore.password=valid_pasword

Am I doing something wrong ? Thanks
