CRX/DE console doesn't show node-tree in the AEM 6.2 for the run mode - Author, CRX3 and samplecontent

Issue: CRX/DE light console doesn't show nodetree
- Run mode for Author instance as follows:

sling.run.mode.install.options=author|crx3|samplecontent
- Post the installation of Author instance in crx/de console shows nothing in the tree-node, refer the below screenshot.
http://localhost:4502/crx/de/index.jsp

Solution:
- Go to the http://localhost:4502/system/console/configMgr
- Search for Apache Sling DavEx Servlet
- Root path shows only /Server as shown in the below screenshot.


- Change the root path from /server to /crx/server and save it.



- Go back to the /crx/de console, You will be able to see the node-tree as shown below.
