Style error after importing SLD of QGIS in GeoServer Layer

Question

I have a layer in GeoServer which opens when default style like "polygon" is selected in the publishing menu

Layer opening with default style

but when I change its style in WMS Settings, for which I have created a new style by importing the SLD of same dateset from QGIS, it shows the error like,

ERROR: invalid input syntax for type double precision and the layer does not open.

error with new SLD

However while Validating the imported SLD, no errors were encountered.

validation of New SLD

The SLD used is as follows:
