In a Java adapter when we create a new tag using Push Tag (POST) we always get a "The target resource 'PushTag' already exists" 409 response and an error in the log even though the new tag is successfully created

Is this a known issue? Is there a work-around?

In the logs the sequence is like this;

    Is the create Tag being called only once? Could you confirm the call is made only once? If or not, you could verify if the tag exists already before issuing a create tag. – Srinivasan Nanduri Oct 16 '17 at 15:39
  • Yes, the create call is made only once. First we verify if the tag exists or not, using GET call to /imfpush/v1/apps/myApp/tags/theTag Only if that returns a 404 (as shown in the log snippet) do we make the POST call to create tag – Michael Thompson Oct 16 '17 at 15:56
  • You mentioned Java adapter. Are you really calling the REST endpoint from within the Java adapter? 409 refers to concurrency failures - hence the query – Vivin K Oct 16 '17 at 18:09
  • Yes, we are really calling the REST endpoint from within the Java adapter. The adapter has to get messages to be sent from a queue. If the message is for a tag that hasn't already been created, then the adapter creates it. – Michael Thompson Oct 16 '17 at 21:03
