iServer服务请求featureResults，空间面及属性过滤出错
url:：/iserver/services/data-HYL_KSJ/rest/data/featureResults
参数如下：
{
"getFeatureMode":"SPATIAL_ATTRIBUTEFILTER",
"datasetNames":["HYL_KSJ:HYLSQ_FW"],
"geometry":{"id":0, "style":null, "parts":[1], "coordinates":[[[165.23421443892352, 24.66142313142544], [165.16758926982106, 24.618632233878454], [165.2421042613527, 24.554972004762938], [165.30031361871042, 24.616527763436377], [165.23421443892352, 24.66142313142544]]], "type":"POLYGON"}, "attributeFilter":"XIAN like '%25武江区%25'",
"spatialQueryMode":"INTERSECT"
}
报错内容是getFeatureByBuffer方法中传入的参数为空。
不是缓冲区查询，怎么会报这个错误，不解？
