Facebook API (#803) Cannot query users by their username. What's wrong?

Question

Python

Good day everyone!
Installed Facebook API in Python
https://github.com/mobolic/facebook-sdk/blob/maste...
import facebook Everything works.
Example works too
access_token = ''
# Look at Bill Gates's profile for this example by using his Facebook id.
user = 'BillGates'
graph = facebook.GraphAPI(access_token)
profile = graph.get_object(user) posts
= graph.get_connections(profile['id'], 'posts')
error
For example user='profdanielamatos '
GraphAPIError: (#803) Cannot query users by their username (profdanielamatos)
Help me figure out what's wrong?
Thanks in advance!

Answer 1

Facebook has disabled the ability to contact by username.
And "BillGates" is not the username of the user, but the short address of the public page.
That is, username only works with pages. "cnn" will work, "vasyapetrov" will no longer work.
