Some js and css file not loading on the page
Some .js and .css files are missing from your AEM pages or from AEM's UI.
This could be caused by a few things:
- The xpath query  used by the AEM Client Library Manager (HTMLLibraryManager) is using some index other than the /oak:index/nodetype index.
- The nodetype index is failing to get updated or is corrupted.
- The clientlibs-service user's permissions are missing.
I. Check the service user permissions
Review this article in case the clientlibs-service user permissions are missing.
II. Check that the query is getting correct results
Go to Tools => Query.
In the bottom Query box, enter this query:
If you found that the results excluded the missing client library then go to http://aem-host:port/libs/granite/operations/content/diagnosis/tool.html/granite:queryperformance.
Enter the query again and click "Explain".
The output shows you which index is used to execute the query. If the index listed is not the "nodetype" index then something is wrong.
If the correct index is picked but fails to return the correct result then it is corrupted. You will need to reindex the nodetype index.
