RabbitMQ: Queue not getting declared for one of the fanout queues

Hi there, I am facing an issue with consumer declaration in the rabbitMQ fanout design, please take a look below details and let me know if there is any fix for this, thanks in advance.

I have the following configs for a fanout implementation:

Producer

spring.cloud.stream.bindings.sendUpdate-out-0.destination: update.v1.send-event
spring.cloud.stream.rabbit.bindings.sendUpdate-out-0.producer.exchange-type: fanout

consumer in service A

spring.cloud.stream.bindings.onABCUpdate-in-0.destination: update.v1.send-event
spring.cloud.stream.bindings.onABCUpdate-in-0.group: mail
spring.cloud.stream.rabbit.bindings.onABCUpdate-in-0.consumer.exchange-type: fanout
spring.cloud.stream.rabbit.bindings.onABCUpdate-in-0.consumer.dlqName: update.v1.send-event.mail.dlq
spring.cloud.stream.rabbit.bindings.onABCUpdate-in-0.consumer.auto-bind-dlq: true
spring.cloud.stream.rabbit.bindings.onABCUpdate-in-0.consumer.republishToDlq: true

#consumer in service B
spring.cloud.stream.bindings.onXYZUpdate-in-0.destination: update.v1.send-event
spring.cloud.stream.bindings.onXYZUpdate-in-0.group: sms
spring.cloud.stream.rabbit.bindings.onXYZUpdate-in-0.consumer.exchange-type: fanout
spring.cloud.stream.rabbit.bindings.onXYZUpdate-in-0.consumer.dlqName: .update.v1.send-event.sms.dlq
spring.cloud.stream.rabbit.bindings.onXYZUpdate-in-0.consumer.auto-bind-dlq: true
spring.cloud.stream.rabbit.bindings.onXYZUpdate-in-0.consumer.republishToDlq: true
`

The consumer in service A is working fine and it is the only consumer in that service. However, the consumer in B is not working and exists with two other consumers related to different functionality. To add service-B's queue to the fanout exchange I had to add the following config, which was is required in any other consumers we are having.

spring.cloud.stream.input-bindings:onXYZUpdate;

The consumer declaration is as follows:

@Bean public Consumer<TestMessage> onXYZUpdate(Strategy strategy) { return message -> { try { strategy.execute(message); } catch (Exception e) { LOG.error(e.getMessage(), e); } }; }

All the consumer declarations and the configs are similar, but an inbound queue is not getting declared for this consumer. I know that because the other two consumers in the service are logging the below log lines, but this one doesn't.

20:46:23.352 [main] [MEMBER_ID: ] [USER_ID: ] [] INFO RabbitExchangeQueueProvisioner.doProvisionConsumerDestination: [line:243] - declaring queue for inbound: <bindingName>.<group name>, bound to: <destination>
