marklogic - 我在处理 ZIP 时收到 500 个内部服务器错误 (XDMP-CHILDNODEKIND)

Question

我们有 rest 扩展，其中 post 方法的参数之一是我们想要处理的 zip，但我收到错误 500。以下消息显示在响应中。ZIP 由一些 json 和图像和 pdf 组成。是否有任何解决方法可以使其运行。

这是我在 PROD 环境中重现的情况：

扩展代码：

declare 
%roxy:params("")
%rapi:transaction-mode("update")
function dmc:post(
    $context as map:map,
    $params  as map:map,
    $input   as document-node()*
) as document-node()*
{
  let $_ := xdmp:log("**********")
  let $_ := xdmp:log($context)
  let $_ := xdmp:log("**********")

  let $_ := xdmp:log("**********")
  let $_ := xdmp:log($params)
  let $_ := xdmp:log("**********")

  let $_ := xdmp:log("**********")
  let $_ := xdmp:log($input)
  let $_ := xdmp:log("**********")

  let $_ := xdmp:log("**********")
  let $_ := xdmp:log(xdmp:get-request-field-content-type("rs:file"))
  let $_ := xdmp:log("**********")

  let $_ := map:put($context, "output-types", "application/xml")
  let $_ := map:put($context, "output-status", (201, "Created"))
  let $name := map:get($params, "name")
  let $file := map:get($params, "file")
  return document{c:my-function($name, $file)}
};

模块代码：

declare function c:my-function($name as xs:string, $file as binary()) as xs:string{

    let $my-name := $name
    let $my-file := $file
    return $my-name
};

错误消息在这里非常清楚 - 例如，您不能有包含二进制内容的子节点，即不能将图像作为 XML 文档的子节点

这已经得到了更详细的回答：
