Connector version showing as "null"

[oliallan14]

Hey

We are installing scylladb sink connetor via confluent hub cli.
While validating the installed connector plugin we can see the version of connector as "null" as shown below;

curl http://ABC:8083/connector-plugins

{"class":"io.connect.scylladb.ScyllaDbSinkConnector","type":"sink","version":"null"},

Looks like it might be a bug in:
