AEM 6.3 ResourceProvider resourceResolve.getResource always returns null

I am having trouble solving the following issue: I have a ResourceProvider with a root mapped at '/synthetic/config'. In the getResource() method I retrieve the resourceResolver and try to fetch the resource (this resource does exists!) but this never succeeds, I always get a 'null'.

Here is my code (I based mine on https://svn.apache.org/repos/asf/sling/trunk/launchpad/test-services/src/main/java/org/apache/sling/launchpad/testservic…  ):

@Component

@Service(value=ResourceProvider.class)

@Properties({

        @Property(name = ResourceProvider.PROPERTY_NAME, value = "Planets"),

        @Property(name = ResourceProvider.PROPERTY_ROOT, value= ConfigResourceProvider.SYNTHETIC_CONFIG_ROOT)

})

public class ConfigResourceProvider extends ResourceProvider<ConfigResourceProvider.DoesNotNeedAContext> {

    public static final String SYNTHETIC_CONFIG_ROOT = "/synthetic/config";

    @Override

    public Resource getResource(ResolveContext<DoesNotNeedAContext> resolveContext, String s, ResourceContext resourceContext, Resource resource) {

        Resource resource1 = resolveContext.getResourceResolver().getResource("/content/we-retail");

        return null;

    }

    @Override

    public Iterator<Resource> listChildren(ResolveContext<DoesNotNeedAContext> resolveContext, Resource resource) {

        return null;

    }

    /** If this provider required a context this would be more elaborate,

     *  but for this simple example we don't need one.

     */

    public static class DoesNotNeedAContext {

    };

}

How can I fix this? Thanks in advance!

IS that the value that appears when you open the Manifest file in the bundle? You need to make sure they match exactly. Also make sure the system user has the correct permissions. These are 2 things that can explain the null.
