How to setup CORB

How can I construct this XQuery to run in a CORB job? The 2nd module to process each doc with a matching candidate URI is not working.

URIS Module

(:a module to select the candidate URIs to process:)
xquery version "1.0-ml";
declare variable $target-collection := "/activity";  
declare variable $update-collection := "/activity/analytics-read-added"

let $uris := cts:uris( (),
                       (),
                       cts:and-query((          
                           cts:collection-query($target-collection),
                           cts:not-query(cts:collection-query($update-collection))
                        ))
)
return (count($uris), $uris)

Process Module

(:a module to process each doc with a matching candidate URI:)
declare variable $URI as xs:string external;

 xdmp:document-add-permission($URI,xdmp:permission("act-read-role","read")),

xdmp:document-add-collections($URI,$update-collection)

Solution

There are a couple of small issues with your process module:

the variable $update-collection declared in the URIS Module also needs to be declared in the Process Module, if you want to use it.
The function to add permissions is misspelled. It is plural: xdmp:document-add-permissions()

Applying those changes to the Process module:

xquery version "1.0-ml";
(:a module to process each doc with a matching candidate URI:)
declare variable $URI as xs:string external;
declare variable $update-collection := "/activity/analytics-read-added";

 xdmp:document-add-permissions($URI, xdmp:permission("act-read-role","read")),
 xdmp:document-add-collections($URI, $update-collection)

If you need to troubleshoot and investigate why your Process Module isn't working, it is sometimes easiest to paste the content of the Process Module XQuery into Query Console, assign a value to the $URI variable, and execute in QConsole.

For example:

declare variable $URI as xs:string external := "/some/test/doc.xml";
