HI Team,

We have upgraded our AEM publisher from 6.1 to 6.3. We can see it is successfully upgraded and all bundles are active but still not able to access crx/de

error is below:

14.03.2019 10:59:55.680 *ERROR* [qtp792333139-60] org.apache.sling.engine.impl.SlingHttpContext handleSecurity: Possible reason is missing Repository service. Check AuthenticationSupport dependencies.
