hi, I’m trying to do the Kafka Connect course, and at this lesson [Create Confluent Managed Kafka Connectors with the Connect API](https://developer.confluent.io/courses/kafka-connect/connect-api-hands-on/)  
a few problems:

1. step 14 of preparation steps is still not yet updated to the new command syntax for `confluent kafka client-config create java`(this was raised at [Confluent kafka client-config not found](https://forum.confluent.io/t/confluent-kafka-client-config-not-found/8425))
2. the endpoint of steps 7,8 of the exercise should be different for every user, not always `https://pkc-6ojv2.us-west4.gcp.confluent.cloud:443`, it should be taken from the `"http_endpoint"` from the response of the previous get clusters of environment curl command
3. the command in step 16 to create a MySqlSinkConnector with `"connection.host": "ec2-54-175-153-98.compute-1.amazonaws.com",` has given me an error response: `"validation_errors": ["connection.host: Could not connect to database. ...", "ssl.truststorefile: Could not connect to database. ..."]` - this one I do not know how to resolve / workaround

please help…
