Hi @akg17, it looks like the app is getting denied when trying to add the txError topic subscription to the queue. I’m assuming this is your spring.cloud.stream.bindings.<name-in-0>.destination value? The destination that you specify on the binding is used to create the queue name (per the queue naming convention) but it also is the first topic subscription added to the queue.
Your client-username has an acl-profile assigned to it which allows for fine grained access control of the username. You can read more info about it here. And you can edit it in the PubSub+ Manager under the “Access Control” menu. Note the “Subscribe Default Action” setting at the top. If it’s “Allow” then whatever topics you add below are what your client can’t subscribe to. If it’s “Disallow” then you’ll want to add the ones you want the client to be able to subscribe to.
