MarkLogic 10 - managed document throwing exception on dls:document-checkout-update-checkin

Question

I have managed document named 123456.xml and I am trying to update it with dls library function as below,

declare variable $uri:= "/abc/123456_xml_versions/1-123456.xml";

dls:document-is-managed($uri),
dls:document-checkout-update-checkin($uri, $xml, 'Update', fn:true())

Above script snip is throwing below exception,

[1.0-ml] DLS-DOCUMENTVERSION: (err:FOER0000) Cannot update or checkout document version /abc/123456_xml_versions/1-123456.xml

This is an existing migration operation of the application which is updating all versions of the document.

Answer 1

Don't give DLS functions URIs from the versions directory. Those URIs are managed by DLS. Just give it the canonical URI of the document you want to update, and DLS will automatically increment the version for you:

declare variable $uri:= "/abc/123456/123456.xml";
