我最近迁移到 MarkLogic 9.0.2，现在我将所有触发逻辑从 xqy 迁移到 sjs。

这是我的问题，我在 sjs 中有一个触发器，它是在 xqy 中创建的，如下所示：

xquery version "1.0-ml";

import module namespace trgr="http://marklogic.com/xdmp/triggers"
   at "/MarkLogic/triggers.xqy";

xdmp:log("TRGR: Installing tp-firstTimeSeen"),

trgr:create-trigger("tp-01-firstTimeSeen", "Trigger to Alert First time a device is seen by a tp-sensor ",
  trgr:trigger-data-event(
    trgr:collection-scope("tresspasser"),
    trgr:document-content("create"),
    trgr:post-commit()
  ),
  trgr:trigger-module(xdmp:database(), "/", "/triggers/tp-01-first-time-only.sjs"),
  fn:true(), (: enabled / disabled :)
  xdmp:default-permissions(),
  fn:false()
)

触发代码尝试查找刚刚创建的文档以检查某些内容。

请注意，uri 似乎“就在那里”......

sjs中的触发代码：

declareUpdate();

// load utilities
//var scc = require("/lib/sccsslib.sjs");

var uri;

xdmp.log(fn.concat('TRESSPASSER-TRIGGER ON ',uri, ' was triggered...'))

var data = fn.doc(uri);
xdmp.log(fn.concat('data : ',data))
var event = data.toObject();
var sensorId = event.event.sensorid;
var sData = event.event.sensordata;

for (i = 0; i < sData.length; ++i){
  // search for each mac adres in the database
  var mac = sData[i].mac;
  // search all events from this sensor
  var hit = cts.search(cts.andQuery([cts.collectionQuery("tresspasser"),
                                        cts.jsonPropertyValueQuery("sensorid",sensorId),
                                        cts.jsonPropertyValueQuery("mac",mac)])).toArray();
  if (fn.empty(hit)) {
    // we have never seen this mac before
    // send alert
    xdmp.log('TODO: SEND ALERT')
  } else {
    xdmp.log(fn.concat('SEEN BEFORE : ',mac))
  }
};

;

现在触发器被激活并被触发，但在日志中数据对象为空。

日志：

如果我在查询控制台中执行相同的代码，它就可以工作......

我错过了什么？
