Environment

AEM 6.2 and later versions

Cause

The clientlibs-service user is missing or missing permissions.

Resolution

To get rid of the AccessDeniedException and fix the issue, follow these steps:

Go to http://host:port/crx/de/index.jsp web app and log in as admin.
Browse to the folders below and validate that clientlibs-service user has these permissions:
- /apps Allow jcr:read
- /libs Allow jcr:read
- /etc Allow jcr:read
- /var/clientlibs Allow jcr:read, rep:write
To view permissions, browse to the node you want to view or modify permissions for. Then, on the lower-right panel of CRXDE click the Access Control tab.

If the clientlibs-service user itself is missing, then go to a working AEM instance and create a package of the path /home/users/system/clientlibs-service. Then install that to your broken instance.
