org.apache.sling.api.SlingException: Cannot get DefaultSlingScript: Identifier com.torrid.aem.dynamicmedia.core.models.ReviewDashboardPageModel cannot be correctly instantiated by the Use API

Whenever I try to add '@Reference' of a service in other java file getting the above error.

If I remove the reference then everything works fine.

ERROR:

Appreciate any help regarding the issue.

Hi @nandan123 ,

Looks like you are trying to inject an OSGi service into the sling model.

You need to use @OSGiService annotation instead of @Reference.

Check the documentation here:-

https://sling.apache.org/documentation/bundles/models.html 

https://sling.apache.org/apidocs/sling8/org/apache/sling/models/annotations/injectorspecific/OSGiSer... 

Also, check if the service you are trying to inject is available on the console.

Hope this helps!

Regards,

Nitesh

The issue is resolved,

I was referencing Service1 which has reference of Service2 in Service2 itself, which some how got in loop.

Thank you,

Nandan
