Adapting metadata node to object is returning null

I need to adapt document metadata node to an object. The code is as below. But the object returns null. Did anyone face similar issue?

Resource resource = resourceResolver.getResource(destinationPath+"/"+JcrConstants.JCR_CONTENT+"/metadata");

DocumentInfo documentInfo = resource.adaptTo(DocumentInfo.class);

Hi,

I don't know the DocumentInfo class, can you please give the full package name? Is there an adapter factory available for this at all? Check localhost:4502/system/console/adapters if an adapter with adapter class "Resource.class" and adaptable class "DocumentInfo.class" is registered.

adaptTo() is allowed to return "null" in case the adaption fails. Depending on the adapter factory the reasons are logged or not. So we clearly need to know much more information about the resource (or sub-resources) you are trying to adapt.

Thanks Jorg. I could figure out the issue now. DocumentInfo is a custom class that we have created. We are posting assets to DAM and have additional properties added to metadata.

Currently we are migrating from AEM 6.1 to 6.3. I missed the configuration for making DocumentInfo adaptable. I have added the same and now it is available in "/system/console/adapters" and working as expected.
