"Root node is not accessible" error when Test Connection is triggered in default replication agent on Author

[ak481808]

Hello Everyone,

We upgraded from AEM 6.0 to AEM 6.3 (Not sure if this is an issue related to AEM 6.3)

The default replication agent is not working as expected. When Test Connection is done, it throws below error in the logs:

16.02.2018 17:55:24.549 *ERROR* [10.150.44.28 [1518783924487] GET /etc/replication/agents.author/publish.test.html HTTP/1.1] com.day.cq.cq-audit [com.day.cq.audit.impl.DefaultAuditLog(1301)] The activate method has thrown an exception (javax.jcr.AccessDeniedException: Root node is not accessible.)

javax.jcr.AccessDeniedException: Root node is not accessible.

After this, it keeps on throwing below error -

16.02.2018 13:14:15.653 *ERROR* [FelixDispatchQueue] com.day.cq.wcm.cq-msm-core FrameworkEvent ERROR (org.osgi.framework.ServiceException: Service factory returned null. (Component: com.day.cq.wcm.msm.impl.RolloutExceptionHandlerImpl (1734)))

I have tried troubleshooting steps -

1. Did a ping from author to publish VM, Ping is fine.

2. Did telnet from author to publish VM, that is also fine.

3. Checked all access in publish server for the admin user, all access is as expected)

4. The replication queue is clear.

5. However, when I do a wget from author to this URL I get this -

wget http://<publishURL>:4503/bin/receive

--2018-02-16 18:16:17--  http://<publishURL>:4503/bin/receive

Connecting to <publishURL>:4503... connected.

HTTP request sent, awaiting response... 401 Unauthorized

Authorization failed.

Could this be the problem? Please let me know if someone has faced the same sort of issue.

I got the same issue while triggering a custom WF. I suppose it's issue with Launcher unable to get the node but not sure. Let me know if you were able to solve this and how.

Kunwar​ - is this a known issue. This does not happen on fresh installs - we have tested AEM Rep on 6.3/6.4 with no issues. It appears to be some sort of upgrade issue.

[Kunwar · Accepted solution]

No it's not a known issues. Something is wrong with the repository for sure, deeper analysis on the logs would he. I'd suggest to open a daycare ticket for this.

Looks like a permission issue. Can you validate the permissions of the service users "replication service" to check if you have adapted them? Compare the permissions of your migrated instance to a fresh installation of AEM 6.3.

For me these errors keep popping up even if I add a new asset or delete an existing. So any action on a node from DAM triggers this.

[Jörg_Hoh]

Can you post the full stacktraces?

some where in code login user is trying to access root node

for eg: Node root = session.getRootNode();

To check login in  as http://localhost:4502/useradmin 

relative path as : /useradmin

below is the example of without root node access permission : see the first line in the folder path no root access

for this logged in user provide at least read access permission as below :
