# including SRID in WKBWriter in Shapely doesn't work

I want to encode coordinates of LineString in WKB with the SRID included

 wkbwriter = shapely.geos.WKBWriter(shapely.geos.lgeos, big_endian=False, include_srid=True)

geo = wkbwriter.write_hex(LineString(geometry_obj['coordinates']))


but it is the same exact as

shapely.geometry.shape(geometry_obj).wkb_hex


and does not include the SRID in the encoding, causing issues when trying to store it in postgis with column Geometry('LineString', 3857)

what am I doing wrong?
