Downloading saved posts, graphql query gets redirected to homepage and fails

[tamasv]

Describe the bug
Downloading saved posts is currently broken.
Profile.get_saved_posts() or cli :saved gets redirected to www_instagram_com ( from /graphql/query/? endpoint ) and throws a "JSON Query to graphql/query: Expecting value: line 1 column 1 (char 0)" error.
