Hi , I have two nodes both of which publish different custom defined messages. Node A publishes message A , and Node B publishes message B. Can node A subscribe to message B while node B subscribes to message A. I am getting error a fatal error saying that the No such file or directory for the custom defined message. When i disable node B's subscribing the message A, node can successfully publish the message B. Any help is appreciated.

It is possible to make topics go in a loop as described. It isn't possible to declare circular dependencies between packages.

It sounds like you have a typo or have forgotten to include a package dependency somewhere.
