Custom propertie's values are not updated for workflow metadata

Question

Hi,
I've a requirement where I need to add and update some properties. to /etc/workflow/instance/<Instancename>/data/metadata node.
I've two workflow Process steps,
Process step 1:
    Adds some properties to metadata.
Process step 2:
    Updates the propertie's values which are added in Process step 1.
But the issue is update is not working when the node is /etc/workflow/instance/<Instancename>/data/metadata.
i.e. In the step 1, Properties are added to metadata node but In the step 2 propertie's values are not updated to the same node.
Here is my process code:

    @Reference
    private ResourceResolverFactory resourceResolverFactory;
          public void execute(WorkItem workItem, WorkflowSession wfsession, MetaDataMap metadata)
                              throws WorkflowException {
                    System.out.println("Testing");
        try{
            ResourceResolver resolver;
            resolver = resourceResolverFactory.getAdministrativeResourceResolver(null);
            String instancePath = workItem.getWorkflow().getId();
            Node instanceNode=null;
            Session jcrSession = wfsession.adaptTo(Session.class);
           String payload = (String) workItem.getWorkflowData().getPayload();
           //instanceNode=JcrResourceUtil.createPath(payload+"/jcr:content", "nt:resource","nt:resource", jcrSession, true);
                              instanceNode=JcrResourceUtil.createPath(instancePath+"/data/metaData", "nt:resource","nt:resource", jcrSession, true);
                              System.out.println("Test: instance PAth:"+instanceNode.getPath());
            Resource resource = resolver.getResource(instanceNode.getPath());
                if(resource != null)
                    PersistableValueMap valueMap= resource.adaptTo(PersistableValueMap.class);
                    valueMap.put("name", "Rajesh");
                    valueMap.put("id", "A002");
                    valueMap.put("designation","SE");
                    valueMap.save();
                    System.out.println("Name:"+valueMap.get("name"));
                    System.out.println("Id:"+valueMap.get("id"));
            jcrSession.save();
            resolver.close();
        }catch(Exception e)
            System.out.println("Exception:"+e.getMessage());
===================
The code works fine when the node is payload/jcr:content.
Note : Process 1 and Process 2 code is same expect the values I'm passing to the PersistableValueMap.
Any pointers would be more helpful..
Thanks
