GET /api/v1/agents/???/photo return err400

Trying to get desk agent's photo using this query:
curl -X GET https://desk.zoho.eu/api/v1/agents/?????????/photo?orgId=?????
-H "X-com-zoho-subscriptions-organizationid:????"  
-H "Authorization:Zoho-oauthtoken ????"

I always get response code 400.
I have included all necessary scopes in token Desk.settings.READ,Desk.basic.READ,profile.userphoto.READ

URL that i am requesting was returned by GET /api/v1/tickets?include=assignee in the assignee object.
