             Summary: Resolving the error handling scripts should consider the request file extension
                 Key: SLING-7836
                 URL: https://issues.apache.org/jira/browse/SLING-7836
             Project: Sling
          Issue Type: Improvement
    Affects Versions: Servlets Resolver 2.4.20, Launchpad Integration Tests 1.0.6
            Reporter: Eric Norman
            Assignee: Eric Norman


I am expecting that a request to [http://localhost:8080/bogus.json] should return a JSON response with the 404 error details in JSON when the resource doesn't exist.  (also similar behavior should be possible for a .txt or .xml file extension)
 
What I see currently is that SlingServletResolver#handleError ignores the incoming file extension and always returns the error page as html.
 
I would expect that an "errorhandler" script/servlet registered with ("sling.servlet.resourceTypes=sling/servlet/errorhandler", "sling.servlet.extensions=json", "sling.servlet.methods=404") should be preferred when the incoming request has a .json extension, and then use the original html error response as a fallback for all other scenarios.
 
Basically the client should get JSON back when something goes wrong instead of html that won't parse as JSON.
