When you do an xdmp:eval, that is its own request, and the XQuery that you
specify is a separate request. So if you put a try/catch around the eval, it
will catch any errors thrown by the query within the try. For example, if you
run the following:
xquery version "1.0-ml";
try{
xdmp:eval("blah")}
catch ($e) { $e }
It will return the XML stack trace from the inner query (which is a syntax
error in this case - XDMP-CONTEXT).
If the inner query ran and was canceled, that exception would be caught be the
outer program (the eval).
Clear as mud?

Hi Danny,
What you meant by both request?

If this is wrapped in an eval or an invoke, then it is probably possible to
catch this exception. But likely both requests would be canceled at the same
time so it might be tricky...

Hi Selva,
It is an indication that the request was terminated (canceled) from outside the
request, so you cannot catch that exception from inside the request itself. It
could be that the user in the browser canceled the request (by interrupting the
load), or some admin killed the task on the MarkLogic host. In case the user
canceled it, not sure you can catch that in your user interface. A server-side
cancel should I think return a 500 with XDMP-CANCELED in the response body..
Kind regards,
Geert

I am trying to load 275 mb files into marklogic. I got the below error message
from my logs.
XDMP-CANCELED: cts:search(fn:doc(),
cts:and-query((cts:collection-query($dictionary),
cts:collection-query("Process")))) -- Canceled request "/process.xqy"
I have a interface to upload the marklogic file. Can i catch this exception in
my interface?
Best Regards,
Selva
