browse wfs layers模块，加载要素图层报 Invalid XML，这是为什么

[chinathingsboard]

demo中browse wfs layers模块，加载wfs要素图层出现 Invalid XML错误，抓包发现请求是成功的，这个要怎么解决。
三个必要参数分别是：service=wfs&version=2.0.0&request=GetFeature
OutputFormat参数里，试过以下格式都不行:
application/gml+xml; version=3.2
gml3
GML2
KML
text/xml; subtype=gml/3.1.1
SHAPE-ZIP
application/json
application/vnd.google-earth.kml xml
application/vnd.google-earth.kml+xml
text/xml; subtype=gml/3.2
text/xml; subtype=gml/3.1.1
text/xml; subtype=gml/2.1.2
text/javascript,csv,gml32,json
