Inheritance Value Map in Experience Fragment

Question

I have experience Fragment Footer/master.

There is a tag field (cq:tags) available on both Footer and Master. I have authored on Footer but not on master

Now if I try to run a workflow on master and try to fetch cq:tags using InheritanceValueMap I am not able to fetch from Footer properties.

InheritanceValueMap inheritanceValueMap = new HierarchyNodeInheritanceValueMap(resource);
String[] tagValue = inheritanceValueMap.getInherited("cq:tags", String[].class);

I've tried by initiating a Workflow Model on the master node. And I can have the value of cq:tags I have set on the parent Footer Experience Fragment.

My Workflow Model has a custom WorkflowProcess. Here is the simplified version of the code -

@Slf4j
@Component(service = WorkflowProcess.class, property = {"process.label=Test Workflow Process"})
public class TestProcess implements WorkflowProcess {
    @9944223
    public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap metaDataMap) throws WorkflowException {
        try {
            Session session = workflowSession.adaptTo(Session.class);
            WorkflowData workflowData = workItem.getWorkflowData();

            if ("JCR_PATH".equals(workflowData.getPayloadType()) && workflowData.getPayload() != null) {
                String payloadData = workflowData.getPayload().toString();
                String pagePath = session.itemExists(payloadData) ? payloadData : StringUtils.EMPTY;

                Resource resource = workflowSession.adaptTo(ResourceResolver.class).getResource(pagePath);
                String[] tagValue = new HierarchyNodeInheritanceValueMap(resource).getInherited("cq:tags", String[].class);

                log.info(String.join(", ", tagValue));
            }
        } catch (RuntimeException | RepositoryException e) {
            log.error("error due to {}", e.getMessage(), e);
        }
    }
}
