Subscribing with #noexport fails to receive messages

in PubSub+ Event Broker #1

Per the Solace docs, if I prefix my topic with "#noexport," I should be able to subscribe to the topic, but the subscription will not be advertised to adjacent nodes by MNR or DMR.

https://docs.solace.com/Messaging/No-Export.htm


But I'm having trouble getting that to work. In the below example, everything takes places on the same broker. Here is my publisher:

2022-10-20 13:36:38 INFO c.c.p.msg.solace.SolacePublisher: Started publisher on topic <_/1/ps/msg/sandbox/ch12/my/test> sow <false>


I can successfully subscribe to those messages if I use a matching topic string:

2022-10-20 13:42:03 INFO c.c.p.msg.solace.SolaceSubscriber: Started subscriber on topic <_/1/ps/msg/sandbox/ch12/my/test> sow <false> mode <GUARANTEED>


But if I prefix it with "#noexport," I see nothing:

2022-10-20 13:38:44 INFO c.c.p.msg.solace.SolaceSubscriber: Started subscriber on topic <#noexport/1/ps/msg/sandbox/ch12/my/test> sow <false> mode <GUARANTEED>

    Whoops! This was a misunderstanding on my part. I replaced the "_" placeholder in my topic string, but I should not have. This works:

    2022-10-20 14:11:48 INFO c.c.p.msg.solace.SolaceSubscriber: Started subscriber on topic <#noexport/_/1/ps/msg/sandbox/ch12/my/test> sow <false> mode <GUARANTEED>

    Thanks for sharing @alanbuttars. Glad you figured it out and I'm sure someone else will have the same issue in the future and find this :)
