Dynamically set topic name and Kafka Brokers in PublishKafka processor

[#1]

Hi,

I am using the PublishKafka processor in nifi to publish JSON data in Kafka. I want to set Kafka Server and topic name details from attribute values. I am not able to do this. Its giving "no resolvable bootstrap urls given in bootstrap.servers " error. Only hardcoded values of the Kafka server and the topic name is working.

I am getting the below error.
