	playlist_id, note=f'Downloading page {page_idx}', query=query)
	except ExtractorError as e:

returns something like

{'code': -352, 'message': '风控校验失败', 'ttl': 1, 'data': {'v_voucher': 'voucher_45ccfacf-4359-4103-**************'}}

where the message means something like "Risk control verification failed", i.e. they suspect you're a bot.
So raise an error similar to code -401 above and ask the user to use cookies.
