I'm trying to use GeoFeatureModelSerializer, along with QueryFieldsMixin from djangorestframework-queryfields
as follows:

class gauge_station_source_data_Serializer(QueryFieldsMixin, GeoFeatureModelSerializer):

However, when I specify ?fields=field1,field2 in my url, it still returns all the fields available, instead of just field1 and field2.

I can use QueryFieldsMixin without GeoFeatureModelSerializer, on a none geospatial model, and it works fine.
