SOLVED WLSDM not able to read Weblogic Domain

[valeC]

I successfully installed WLSDM in my dev environment. I get the relevant messages both in the admin server log and managed server log hosted in the same machine:

MS:

I then tried to go through the wizard in WLSDM console and got a SEVERE error while trying to read Weblogic domain. This is the excerpt from the WLSDM log:

####<Oct 16, 2021 11:18:34 AM CEST><SEVERE><WLSDM><BEA-000000><null

java.lang.NullPointerException
        at com.wlsdm.Q.K.getDeployedJMSServers(MetricUtilities.java:1326)
        at com.wlsdm.frontend.provider.WA.getJMSServerList(MetricsData.java:489)

        at javax.servlet.http.HttpServlet.service(HttpServlet.java:707)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:820)

From the WL console I am able to see that the JMS server targeted to the running MS is healthy.
Wizard does not proceed and is stuck at reading Weblogic Domain.
