Yandex ddns, problem getting record_id?

Question

Yandex

I make a request to get a domain DNS record:
curl -H 'PddToken: <my token for administrator>' ' https://pddimp.yandex.ru/api2/admin/dns/list?domain= <name of my domain which is confirmed and ready to work>'
in the output I get:
{"success":"error","error":"unknown"}
I seem to do everything as it tells me https://tech.yandex.ru/pdd/doc/reference/dns- list-...
