I'm migrating code from Spring Boot 1.5.x to 2.0.3.RELEASE.
It uses RabbitMQ to make an RPC style call to a set of remote engines using the convertSendAndReceive(...) method.
All works fine in 1.5, but fails in the migrated code.
The logging initially shows
SimpleConsumer [queue=amq.rabbitmq.reply-to, consumerTag=amq.ctag-39fo5C1y6q8J9OevWDN3_A identity=6ffebba9] started
The message reaches the engine and is handled correctly.
However, the return value is empty and the following is logged
ERROR o.s.amqp.rabbit.core.RabbitTemplate No correlation header in reply
In 1.5 we didn't add a correlation Id to the caller. Do we now need to or is there something else we need to do?
TIA.
