How to locate the node in JCR using uuid from query

This is the error I get.

16.03.2016 12:02:16.413 WARN [xxx.xxx.xx.xxx [1458147736268] GET /en/employees-leaders/employee-s-toolkit2/epd-update/epd-update-archives/caterpillar-news/upcoming-brand-webinarfocusonmarketing.html HTTP/1.1] com.day.cq.wcm.core.impl.LanguageManagerImpl Error while retrieving language property. javax.jcr.AccessDeniedException: cannot read item xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (alpha-numeric)

I am trying to locate the node in JCR using the xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, which I believe is uuid, using a query in AEM.

Is the xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx actually a uuid?
How do I locate the source i.e node, causing the issue?

I tried running a sql with the above id in the jcr, but it returned no result.

//*[jcr:contains(., '91186155-45ad-474-9ad9-d5156a398629')] order by @jcr:score descending

Any other insights would be much appreciated.

Solution

You don't need a query if you know the Node's UUID, just use the Session.getNodeByIdentifier(String id) method.
