expression language not working in nifi update attribute

iam trying to publish data into multiple kafka topics with some conditions but instead of returning value of the expression , whole value passed for the property is coming.

customerTopic should return me the value of the expression but its returning the expression itself

Try that value:

${kafka.topic:contains('alerts'):ifElse('customerTopicKafkaTesting1',${kafka.topic:contains('events'):ifElse('customerTopicKafkaTesting2',${kafka.topic:contains('ack'):ifElse('customerTopicKafkaTesting3','Not_Found')})})}

You forgot to close ${kafka.topic:contains('events')...}
