Hi @sakshi_123,
It sounds like you might be using an older version of the Spring Cloud Stream binder. Can you take a look and see what version you are using? As of this post the latest versions can be found here: Release v2.2.0 · SolaceProducts/solace-spring-cloud · GitHub
That said, the binder does follow a queue naming syntax as defined here: solace-spring-cloud/solace-spring-cloud-starters/solace-spring-cloud-stream-starter at master · SolaceProducts/solace-spring-cloud · GitHub.
