Error on trying to create connector using gadmin in internal kafka

Hi All

I have been trying to read from a confluent kafka topic installed in the same instance where tigergraph is installed. As i am following the below link

But when i create the connection with gadmin. I am getting the following issue.

tigergraph@ip-10-0-0-24:~$ gadmin connector create --c /home/tigergraph/kafka_connector.conf
[ Error] ExternalError (Failed to create connector; No valid connector config found)
