Open Layer ( Geoserver ) Spatial Search not returning any features

Question

I Created one generic layer in the GeoServer for the open layer ( OL3) and add a few features in the same layer, I'm trying to do the spatial search but the call is not returning any features.

Here is the post-call I'm making to WFS ( Geoserver ) URL http://xyz:5002/geoserver/wfs

In Form Data we are sending query parameter

cql_filter : INTERSECTS(geometry,POLYGON((13.222566632788059 78.15759658813475,13.201844057837434 78.15141677856444,13.211202857957346 78.17956924438474,13.222900853445154 78.17888259887692,13.222566632788059 78.15759658813475)))

service : WFS

request : GetFeature

version :1.1.0

typename : layerName

outputFormat : json

srsname : EPSG:4326

---

The result I'm getting

{
    "type": "FeatureCollection",
    "features": [],
    "totalFeatures": 0,
    "numberMatched": 0,
    "numberReturned": 0,
    "timeStamp": "2022-02-03T09:23:51.415Z",
    "crs": null
}

Geoserver I'm using 2.20.2

Can anyone please let me know what is the mistake I'm doing when I doing the spatial search query
