facebook - Graph API dependant query -


having facebook username, need user id access feed, right i'm using call:

https://graph.facebook.com/john.doe

which returns like:

{   "id": "612029xxx",   "first_name": "john",   "gender": "male",   "last_name": "doe",   "link": "https://www.facebook.com/john.doe",   "locale": "en_us",   "name": "john doe",   "username": "john.doe" }

there use id links:

https://graph.facebook.com/612029xxx/links/?access_token=xxx

but make batch request dependant query make 1 call:

 https://graph.facebook.com/batch=[{"method":"get","name":"do-me-first","relative-url":"?id=john.doe",{"method":"get","relative-url":"links","depends-on":"do-me-first"}}]&access_token=xxx

but gives me error: cannot query users username (john.doe).

why can access user info username in single call, , not in dependant one??

p.s.: second query hasn't been constructed, since giving me first error, couldn't know!
