I'm observing the below error on my APIM210 pack after configured it with
IS530 as a key manager(H2 database). I can see both nodes works fine but
still, i m observing the exception in the console of APIM.
Exception in thread "Timer-4" com.google.gson.JsonSyntaxException:

When I do search I found out a similar JIRA[1] where they told about the

Could you please advice on this?
