I used to have an error like this with IOS. My solution is check config key FacebookSDK in file Info.plist ios/name_project/Info.plist. Make sure that is correct with tutorial step 2 of FB: https://developers.facebook.com/docs/ios/getting-started/
You need to log in with the same account on phone as well as the developer account when you're in development mode.
If your mode is set to development,
try login with test users from the facebook developer account
Inside your device logout with any other fb account if it is there.
Follow the quickstart guide in facebook sdk properly.
Then it will ask for facebook login
