XDMP-NONMIXEDCOMPLEXCONT when doing xpath in rest extension

Question

I am trying to do the following

import module namespace search = "http://marklogic.com/appservices/search" at "/MarkLogic/appservices/search/search.xqy";     
let $options := <options xmlns="http://marklogic.com/appservices/search">
                    <additional-query>
                        <cts:collection-query xmlns:cts="http://marklogic.com/cts">
                            <cts:uri>http://ir.abbvienet.com/content-repo/type/envelope</cts:uri>
                        </cts:collection-query>
                    </additional-query>
                    <constraint name="gene">
                        <range type="xs:string" facet="true">
                            <path-index>//Hit[@type='GENE']/@id</path-index>
                            <facet-option>frequency-order</facet-option>
                            <facet-option>descending</facet-option>
                            <facet-option>limit=10</facet-option>
                        </range>
                    </constraint>
                </options>

    return
    $options//search:constraint[@name='gene']

When I do this in query console it works fine.. but when I do the same in my REST extension, I get the following error

<error:xquery-version>1.0-ml</error:xquery-version>
<error:message>Node has complex type with non-mixed complex content</error:message>
<error:format-string>XDMP-NONMIXEDCOMPLEXCONT: fn:data(&lt;constraint name="gene" xmlns="http://marklogic.com/appservices/search"&gt;&lt;range type="xs:string" facet="true"&gt;&lt;path-index&gt;//Hit[@type='GE...&lt;/constraint&gt;) -- Node has complex type with non-mixed complex content</error:format-string>
 <error:retryable>false</error:retryable>
<error:expr>fn:data(&lt;constraint name="gene" xmlns="http://marklogic.com/appservices/search"&gt;&lt;range type="xs:string" facet="true"&gt;&lt;path-index&gt;//Hit[@type='GE...&lt;/constraint&gt;)</error:expr>
 <error:data/>
<error:stack>

Any ideas on why this is the case ?

**** EDIT Added my REST extension below *************

module namespace repoTest = "http://marklogic.com/rest-api/resource/repoTest";
import module namespace search = "http://marklogic.com/appservices/search" at "/MarkLogic/appservices/search/search.xqy";

            let $options := <options xmlns="http://marklogic.com/appservices/search">

            let $facetContraint :=  $options//search:constraint[@name='gene']
            let $_ := xdmp:log("facetContraint :" || $facetContraint)
                return $facetContraint
            }catch($ex) {
                let $log := xdmp:log("ERROR !!!!!")
                let $log := xdmp:log($ex)
                return ()
        }

    return document { $out }
};

declare function repoTest:put($context as map:map, $params  as map:map, $input as document-node()*) as document-node()?
{
    repoTest:notSupportedMsg($context)
};

};

declare private function repoTest:notSupportedMsg($context as map:map) as document-node()*
{
    let $_ := map:put($context, "output-status", (501, "Not Supported HTTP method"))
    let $output := json:object()
    let $errorResponse := json:object()
    let $_ := (
        map:put($errorResponse, "statusCode", 501),
        map:put($errorResponse, "message", "Not Supported HTTP method")
    )
    let $dummpy := map:put($output, "errorResponse", $errorResponse )
    return document {xdmp:to-json($output)}
};

The above code is not a valid REST extension. Can you show how you use the code in your REST extension? — grtjn
I added my REST extension code, all I was doing is returning the output in my extension code — Ravi
Can you also say something about how you invoke your REST extension? Are you by any chance passing in a format=json parameter? That could trigger some automatic conversion logic, and that is probably not anticipating XML, in particular XML in search namespace? — grtjn

I was able to solve my issue, but don;t understand why this happens in Rest extension but not in query console.

In the REST extension, it was failing because of the default namespace to the $options, once this is removed it works.. the way I removed is

functx:change-element-ns-deep($options, '','')

It would be nice if someone can give an explanation as to why my code in the question, works in query console but not in REST extension,
