Nullpointer exception while trying to configure connector in Confluent Control Center

[ghost]

Hi,

i got the message
Caused by: java.lang.NullPointerException
at org.kaliy.kafka.connect.rss.config.UrlListValidator.ensureValid(UrlListValidator.java:18)
at org.apache.kafka.common.config.ConfigDef.parseForValidate(ConfigDef.java:617)
at org.apache.kafka.common.config.ConfigDef.parseForValidate(ConfigDef.java:551)

at org.apache.kafka.common.config.ConfigDef.validate(ConfigDef.java:525)
at org.apache.kafka.connect.connector.Connector.validate(Connector.java:144)

while trying to configure the connector initial in the Confluent Control Center. I think it trys to check for the url before i even can type it in and runs into NullpointerException (See https://github.com/kaliy/kafka-connect-rss/blob/kafka-connect-rss-0.1.0/src/main/java/org/kaliy/kafka/connect/rss/config/UrlListValidator.java) the call for
List urlsAsList = Arrays.asList(urls.split(RSS_URL_SEPARATOR));

This should be handled different to make it able to configure via Control Center.

Setup in Docker-Compose is the usual docker-compose from confluent-community version.

I managed to replicate the issue and will find the root cause and fix it. Thanks for the report!
