Hi @lone_ranger, Queries:How are you getting the session object?If its via service-user, does the user trying to access jcr have all the required permissions?Did you put cache=true is your modelIf yes please remove itWhat all cache clearance you did here?Also as per the error, there could be some null pointer error here. Can you please share/check the log where it says at which line number it is getting a null pointer?Also, what you can do is try any other existing services that are using Query builder API and check if it is working fine. Hope this helps! Thanks,Kiran Vedantam.

Hi @lone_ranger

If it works fine on Publish instance then it should work everywhere. When you say you are using a component, are you trying to use the Query Builder using a Sling Model or using any servlet?

If it's a Model, your page will be cached and if it has any error already cached at the Varnish URL you might be getting the same error.

Thanks!
