Invalid recursion selector value 'metadata-schema'

Hi All,

I am unable to access the metadata schema for the particular asset in AEM 6.2.

I am accessing page as : http://<serverip:4502/<contentpath>/sample.jpg.metadata-schema.json and It through the below error :

Invalid recursion selector value 'metadata-schema'

Cannot serve request to /<contentpath>/sample.jpg.metadata-schema.json in org.apache.sling.servlets.get.DefaultGetServlet

I am not sure if I am missing any configuration here or it is something wrong in my sling mapping.

Please give me any helps!

Thanks.

Hi annaduraim74336024​,

Could you please perform below steps-

1. Access below url-

http://localhost:4502/system/console/components/

2. Search for com.day.cq.dam.core.impl.servlet.MetadataSchemaServlet

Check it's status is it active or not.

3. If it's not present or if it's not active then request will got to DefaultGetServlet which in turn uses the JsonRendererServlet to process your requests with .json extensions.

Since the JsonRendererServlet requires a numeric selector or the infinity selector, it throws the following error.

Invalid recursion selector value <<selector>>

Regards

Just tried in my local server and it works fine(AEM 6.3) -

http://localhost:4502/content/dam/hero-04.jpg.metadata-schema.json

{"jcr:content/metadata/dc:title":{"label":"Title","value":null,"type":null},"jcr:content/metadata/dc:description":{"label":"Description","value":null,"type":null},"jcr:content/metadata/dc:format":{"label":"Type","value":"image/jpeg","type":"String"},"jcr:content/metadata/dc:language":.........

Could you please try in new server without your custom code.

Thanks for the reply. I tried on a different server is working fine. I am failed to get metadata on this server.

This AEM server is configured in MongoDB. I am not sure if I am missing any configuration or wrongly applied metadata-schema here. How to resolve this one?

Could you please upload one of the asset.

As i am not able to reproduce it , it doesnt matter whether you are running with Mongo DB.
