how to download 10m u/v wind

I want to download 10m u/v wind from 'reanalysis-era5-complete', and I set the aera,codes are below,it runs with some errors

#!/usr/bin/env python
import cdsapi
c = cdsapi.Client()
c.retrieve('reanalysis-era5-complete', { # Requests follow MARS syntax
# Keywords 'expver' and 'class' can be dropped. They are obsolete
# since their values are imposed by 'reanalysis-era5-complete'
'date' : '2022-12-30', # The hyphens can be omitted
'levelist': '1/to/137', # 1 is top level, 137 the lowest model level in ERA5. Use '/' to separate values.
'levtype' : 'ml',
'param' : [
'165', '166',
], # Full information at https://apps.ecmwf.int/codes/grib/param-db/
# The native representation for temperature is spherical harmonics 130-T，129-H，157-RH
'stream' : 'oper', # Denotes ERA5. Ensemble members are selected by 'enda'
'time' : [
'00:00', '01:00', '02:00',
'03:00', '04:00', '05:00',
'06:00', '07:00', '08:00',
'09:00', '10:00', '11:00',
'12:00', '13:00', '14:00',
'15:00', '16:00', '17:00',
'18:00', '19:00', '20:00',
'21:00', '22:00', '23:00',
], # You can drop :00:00 and use MARS short-hand notation, instead of '00/06/12/18'
'type' : 'fc',(here I tried an,but failed either)
'area' : '21/105/4/118', # North, West, South, East. Default: global
'grid' : '0.25/0.25', # Latitude/longitude. Default: spherical harmonics or reduced Gaussian grid
'format' : 'grib', # Output needs to be regular lat-lon, so only works in combination with 'grid'!

}, '20221229.grib') # Output file. Adapt as you wish.

And the result is
