V-add-web-domain [Error 2]

I create a domain using the command v-add-web-domain, but I get an error:
v-add-web-domain ‘gift’ ‘gift3.domain.com’ ‘xxx.xxx.xxx.xxx’ ‘yes’ [Error 2]

In this case the domain is created

E_INVALID=2

So some thing is invalid …

How can i understand what is invalid - the domain is created successfully
