我正在使用 nifi 和 marklogic 处理器。我正在尝试将查询处理器与 cts:uri 一起使用……以下是我的 cts:uri 查询
cts:and-query((cts:element-attribute-value-query(fn:QName('http://clarivate.com/schema/wok5.27/public/FullRecord', 'pub_info'),fn:QName('http://clarivate.com/schema/wok5.27/public/FullRecord', 'pubyear'),'2018'), cts:collection-query('dps')))
上面的查询适用于查询控制台...但是在 nifi 中使用时出现以下异常

我在这里做错了什么？
