curl -XPOST -H “Content-Type: application/json” -d ‘{“name”:“User”,“email”:“”,“login”:“user”,“password”:“password”}’ http://admin:admin@localhost:3000/api/admin/users

got this: [{“classification”:“DeserializationError”,“message”:“invalid character ‘\’’ looking for beginning of value”},{“fieldNames”:[“Password”],“classification”:“RequiredError”,“message”:“Required”}]
