I had the same issue but figured it out.
My mistake was using the 'Client Secret' from the Facebook app page.
Instead, you have to click the button to show your 'App Secret', and enter your FB password and use that to make the app_token as follows:
app_token = app_id + '|' + app_secret

Happy scraping :)
