Hi @zankarshah , I am working on a similar issue, let me know if you found a workaround to fix it

Could you also follow the steps mentioned in this articlehttps://experienceleague.adobe.com/en/docs/experience-cloud-kcs/kbarticles/ka-17467

Could you check in status of com.day.cq.replication.impl.servlets.ReplicationServlet/system/console/components in the failing publisher 

Did you create the page from crx and could you confirm whether you have jcr:content under this page node

Hi @Anilkumar9 Try to clear cache http://localhost:4502/system/console/scriptcache and click “clear cache” 

hi @Nimma05 Since you have register the resource change listener for language copy any property change in the registered resources will trigger the listener. The methods which helps to identify the property which got updated is deprecated now. 

Create a ResourceChange Listener to the content fragment folder path and clear the dispatcher cache for your servlet path DispatcherFlusher service. Limitation with this approach is dispatcher cache will be removed regardless of any cf get updated under the given path.

@KannanCh2 1) Question 1 - Deny all and allow only necessary  is a standard whitelisting technique followed to enhance security and for better filter performance2) Question 2 - If you don't follow the deny all and allow necessary approach then you will end up with this code smell  https://github.com...

Use any one of the below condition before updating the property valueSling API String val = "test"; ModifiableValueMap properties = resource.adaptTo(ModifiableValueMap.class); if(modifiableValueMap.get("someproperty").getClass().isArray()) { modifiableValueMap.put("someproperty", new String[]{val})...

The root cause of the above exception is because you trying to set non array value to a multifield property. Initialise an array and add the required value to the array and set the array as the value of the property.
