I belive the documentation is incomplete in this area.
I am looking into it.
Could you provide your app server configuration details and how you upgraded it
from 6.x ? (did you copy it exactly, recreate it, use package manager ?)
In particular
Port
rewriter URL
error handler url
Authentication type (basic/app-level etc)
default error format
Database
Modules DB
Modules Root
There is a core change in 8.0 where some types of HTTP level validation are now
always generated by the core server where in 7.x they were passed to the user
defined error handler.
Specifically any 'HTTP protocol errors', HTTP validation or authentication
errors that occur before the request is sufficiently processed to determine if
the user is allowed to execute the rewriter are now handled internally
according to the precedence documented.
Errors thrown during user error handler execution are similarly handled.
Its not clear which is the case for your example.
Also the setting for default error format only applies to core server generated
errors. Application generated errors can get the value of the default error
format and choose to generate an appropriate format result or not.
If your using the declarative (XML) rewriter you can set the in-effect error
format in the rewriter (overriding the default format).
There are several trace events that report on the resolution and handling of
error messages as they occur. If you enable tracing and add these events then
in ErrorLog.txt you will get a great deal of detail (more than you may want in
a production system).

Have you looked at your rewriter too? Maybe the 401 is for the rewriter, not
the error handler?
Another clue might come from the AccessLog for that app server.

Subject: [MarkLogic Dev General] ML 8 Error Handler Non-Execution |
Unauthorized User
Hi,
I am currently migrating my ML 6.0-5.3 code to ML 8.0-3 and I found that
error-handler for the App-server is not being executed when an unauthorized
user logs in. I did some research and came to this link:
https://docs.marklogic.com/guide/app-dev/appserver-control#id_84264
But this link has no change as compared to ML 6 documentation and it was doing
custom error handling for an unauthorized-user.
https://docs.marklogic.com/6.0/guide/app-dev/appserver-control#id_84264
[cid:[email protected]]
And in error-handler.xqy, it is written like as follows:
let $error as element(e:error) :=
if ( fn:exists($error:errors) ) then
local:handle-thrown-exception()
else
local:handle-general-error()
Also, the app-server default user is assigned with admin role and default error
format in ML 8 as "xml" tried using "html, json, compatible". Hence it has the
execute permissions too. Still Not working... Can anyone please suggest how to
throw custom message for an unauthorized user from the error handler mechanism.
Currently I am getting is:
<error-response xmlns='http://marklogic.com/xdmp/error'>
<status-code>401</status-code>
<status>Unauthorized</status>
<message>401 Unauthorized</message>
</error-response>
Thanks,
Rahul
