I am using Nifi to send messages to IBM MQ Queue. Earlier, after sending messages using PublishJMS processor the format of my messages in MQ was "MQRFH2". So I needed to get rid of the header hence I used (queue:///theQueueName?targetClient=1) to do so. The format filed of my messages now is empty/blank. Also, a long string is appended before the actual message content. I am not sure how to solve this issue.
